Question 2.
Describe the events of prophase – I
Answer:
Meiosis I is longer phase and consists of 5 sub phases namely Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis.
AP Inter 1st Year Botany Study Material Chapter 11 Cell Cycle and Cell Division 1
a) Leptotene :
The nucleus increases in size by absorbing water from the cytoplasm. The chromatin material organises into a constant number of chromosomes. The chromosomes are long, slender and show bead like structures called chromomeres.

AP Inter 1st Year Botany Study Material Chapter 11 Cell Cycle and Cell Division 2
b) Zygotene :
The chromosomes become shorter and thicker. They approach each other and form pairs. This homologous pair is called bivalent and the process of pairing is called synapsis. It is accompanied by the formation of Synaptonemal complex. The synapsis occurs at proterminal point or procentric or random means.

AP Inter 1st Year Botany Study Material Chapter 11 Cell Cycle and Cell Division 3
c) Pachytene :
Bivalent chromosomes now clearly appear as tetrads. This stage is characterised by the presence of recombination modules, the sites of which crossing over occurs between the non-sister chromatids of the homologous chromosomes. Crossing – over is the exchange of genetic material between the two homologous chromosomes. It is also an enzyme mediated process by ‘recombinase’ crossing over leads to recombination of genetic material on the two chromosomes.

AP Inter 1st Year Botany Study Material Chapter 11 Cell Cycle and Cell Division 4
d) Diplotene :
The homologous chromosomes of a bivalent begin to separate from each other except at the sites of cross overs to dissolution of synaptonemal complex. The ‘X’ shaped structures are called chaismata.

AP Inter 1st Year Botany Study Material Chapter 11 Cell Cycle and Cell Division 5
e) Diakinesis :
It is marked by terminalisation of chaismata. In this phase, the chromosomes are fully condensed and the meiotic spindle is assembled to prepare the homologous chromosomes for separation. By the end of this phase, the nuclear membrane breaks down the nucleolus disappears.

The chromatids undergo condensation, contraction and thickening.

Question 4.
Mention the significance of Meiosis.
Answer:

  1. It maintains the same chromosome number in the sexually reproducing organisms.
  2. It restricts the multiplication of chromosome number and maintains the stability of the species.
  3. Maternal and paternal genes get exchanged during crossing over. It results in variations among the offspring.
  4. All the four chromatids of homologous pair of chromosomes seggregate and go over separately to four different daughter cells this leads to variation in the daughter cells genetically.
  5. Variations play an important role in the process of evolution.

AP Inter 1st Year Botany Study Material Chapter 11 Cell Cycle and Cell Division

Question 5.
Which division is necessary to maintain constant chromosome number in all body cell of multicellular organism and why?
Answer:
Mitosis is necessary to maintain constant number of chromosomes in all body cells in multicellular organisms because mitosis results in the production of diploid daughter cells with genetic employment usually identical to that of the parent cell. The growth of multicellular organisms is due to mitosis. Cell growth results in distributing the ratio between the nucleus and cytoplasam.

It therefore essential for the cell division to restore the nucleo-cytoplasamic ratio. A very significant contribution of mitosis is cell repair. Mitotic divisions in the meristametic tissues, the apical and the lateral Meristems, results in a continuous growth of plants throughout their life.

Question 6.
Though redundantly described as a resting phase. Interphase does not really involve rest. Comment.
Answer:
The interphase also called phase of non-apparent division through called the resting phase is the time during which the cell is preparing for division by involving both cell growth and DNA replication. The interphase is divided into three further phases. They are :

i) ‘G1‘ phase :
It corresponds to the internal between mitosis and initiation of DNA replication. In this the cell is metobolically active and continuously grows.

ii) ‘S’ phase :
Synthesis phase marks the period during which DNA synthesis or replication takes place. The amount of DNA per cell doubles. However, there is no increase in the number of chromosomes.

iii) ‘G2‘ phase :
Proteins are synthesized.

Question 7.
Comment on the statement – Meiosis enables the conservation of specific chromosome number of each species even though the process per se. results in reduction of chromosome number.
Answer:
Meiosis is the mechanism by which conservation of specific chromosome number in each species is achieved across generations in sexually reproducing organisms, even though the process per sec periodically results in the reproduction of chromosome number by half. It also increases the genetic variability in the population of organisms from one generation to the next. Variations are very important for the process of evolution.

Question 8.
How does cytokinesis in plant cells differ from that in animal cells?
Answer:
In animal cells, cytokineis is achieved by the appearence of a furrow in the plasma membrane. The furrow gradually deepens and ultimately joins in the centre dividing the cell cytoplasam into two plant cells, are enclosed by a relatively inextensible cell wall. In plant cells, wall fromation starts in the centre of the cell and grows outward to meet the exiting lateral walls. The formation of the new cell wall begins with the formation of cell plate that represents the middle lamella between the walls of two adjacent cells.

Long Answer Type Questions

Question 1.
Discuss on the statement – Telophase is reverse of prophase.
Answer:
Telophase is the final stage of Mitosis in which the chromosomes that have reached their respective poles decondenses and loose their individuality. Chromosomes cluster at opposite spindle poles and their identity is lost as discrete elements. Nuclear membrane assimilates around the chromosome clusters. Nucleolus, Golgi complex and endoplasmic reticulum reform where as in prophase, chromosomal material condenses and organises to form compact chromosomes. Nuclear membrane, Nucleolus, Golgi complexes. Endoplasmic reticulum disappears. Thats why Telophase is the reverse phase to prophase.

Question 2.
What are the various stages of meiotic prophase – I? Enumerate the chromosomal events during each stage?
Answer:
Meiosis I is longer phase and consists of 5 sub phases namely Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis.

11. The chromosome number of daughter nuclei is unchanged.11. The chromosome number of daughter nuclei is reduced to half.
12. Duration of time is less.12. Duration of time is more.

Question 4.
Write brief note on the following :
a) Synaptonemal complex b) Metaphase plate
Answer:
a) Synaptonemal complex :
The homologous chromosomes approach each other and form pairs called Bivalents and the process is called synapsis. The synapsis occurs at the both ends and progresses towards their centromeres called proterminal or the synapsis starts from their centromeres and the pairing progresses towards the end of the chromosomes called procentric or the pairing occurs at various points of homologous chromosomes called Randon synapsis. The paired homologous chromosomes are joined by a thick protein containing frame work called synaptonemal complex (Sc).Sc stabilizes the pairing of the homologous chromosomes and facilitates crossing over and recombination.

b) Metaphase plate :
Metaphase chromosome is made up of two sister chromatids’which were held together by the centromere. Small disc shaped structures at the surface of of the centromeres are called Kinetochores. These serve as the sites of attachment of spindle fibres to the chromosomes that are moved into centre of the cell. Hence all chromosomes lie at the equator with one chromatid of each chromosome connected by its kinetochore to spindle fibres from one pole and its sister chromatid connected by its kinetochore to spindle fibres from the opposite pole. It is called ‘Metaphase Plate’.

Significance of Mitosis :

  1. Growth in organisms is caused by Mitosis.
  2. The daughter cells formed by Mitosis are identical with the mother cell in characters. Hence it it important in conserving the genetic diversity of the organisms.
  3. In unicellular organisms, Mitosis help in reproduction.
  4. The old dead and decaying cells of body are replaced with the help of Mitosis.
  5. It is useful in regeneration of lost parts and for grafting in vegetative reproduction.

Significance of Meiosis :

  1. Meiosis helps in the maintenance of a constant chromosome number from one generation to the next.
  2. Due to crossing over, genetic recombinations are caused which help in the origin of new species and lead to evolution.
  3. It helps in the formation of gametes and is thus useful in sexual reproduction.

Question 4.
Meiosis has events that lead to both gene recombinations as well as mendelian recombinations. Discuss.
Answer:
An organism often many phenotypic fruits in its body; are determined by at least pair of alleles (or) gener During the events of meiosis – I (crossing over) recombination events occur to pass different combination of chromosomes and consequently different combination of characters in both daughter cells.

The random assortment of the genes is due not only to crossing over but also to the random distribution of the chromosomes in first and second division. How ever, since this separation is a random process, the resulting cells will contain different chromosomal combinations even in the abscence of crossing over.

The New Blue Dress Summary in English

A small good act of a person can make others good. It can change the entire complexion of the surroundings. The present story ‘The New Blue Dress” illustrates this.

Gates Avenue was a short and dirty street in Cleveland. The inhabitants of that street were poor. They never tried to improve their living conditions and better their standard of living. There was no tap water supply in Gates Avenue. There were no street lights. There was also no good pavement.

There was a little girl studying in a school in Gates Avenue. She used to wear the same dress during the spring because she had no other dress to wear. Her parents were too poor to buy a pair of new dress to her.

One day the teacher advised the little girl to keep, at least, her face clean. The girl washed her face clean and came to the class the next morning. She looked more beautiful and tidier. The teacher was pleased. She gave the girl a new blue dress. Her parents saw her in her new blue dress and they were also highly pleased. Since then the members of the family started keeping everything clean and tidy. They washed the floor, repaired the fence and made a garden. The neighbours also followed the same. The surroundings were kept clean. They painted their houses.

After a few days, a young minister of a church passed that way. With his help Gates Avenue got a good pavement, tap-water supply and a street light on the corner.

Within six months Gates Avenue was completely changed. It turned into a neat street where respectable citizens lived.

The new blue dress presented by a teacher to a poor girl could change the entire dirty street into a neat one. So we learn from this incident “A good act shall never go unrewarded”.

Question 2.
Justify the following statements with an example.
i) A positive integer is always greater than a negative integer.
ii) All positive integers are natural numbers.
iii) Zero is greater than a negative integer.
iv) There exist infinite integers in the number system.
v) All whole numbers are integers.
Answer:
i) A positive integer is always greater than a negative integer:
Consider
a) 3, -5 are two integers
3 > -5
b) – 10, 1 are two integers
1 > -10
∴ A positive integer is always greater than a negative integer.

ii) All positive integers are natural numbers:
Positive integers = 1, 2, 3, …..
Natural numbers = 1, 2, 3, …..
So, all positive integers are natural numbers.

iii) Zero is greater than a negative integer:
On a number line, for a given pair of numbers the number on R.H.S is always greater than the number on L.H.S.
All negative integers lie on the L.H.S. of zero, on a number line.
As such all negative numbers are less than zero or zero is greater than all negative integers.

iv) There exist infinite integers in the number system:
If we write integer on a number line, as the line extends on both sides endlessly so as the integers.
(Or)
For every integer there exists another integer which is 1 more than the given integer. Hence the integers are infinite.

v) All whole numbers are integers:
Whole numbers : 0, 1, 2, 3,……
Integers: ……, -3, -2, -1, 0, 1, 2, 3,…..

Question 9.
Siva spends 78% of his monthly income. If he saves Rs. 7,700/- per month, what is his monthly income?
Answer:
Let Siva’s monthly income = Rs. x
Percentage of income spent = 78%
Percentage of income saved = 100% – percentage of spent income
= 100% – 78% = 22%
Saved income = 22% of monthly income = 7700
= 22% of x = 7700
⇒ \(\frac{1}{2}\) × x = 7700
⇒ x = \(\frac{7700×100}{2}\)
⇒ x = Rs. 35000
∴ Siva’s monthly income = Rs. 35000

II. Imagine you were the town mouse/ country mouse and write a paragraph describing your visit.

I am a town mouse. I was born there and I spent all my life in the same town. Recently I suffered badly from cough. The doctor advised me to spend a week or two in the countryside. So I wrote a letter to my cousin who lives in a village, expressing my desire to spend a week in his village. He was very happy and invited me to his village with great pleasure. Immediately after receiving the letter I went to the village. He received me at the station. There it was very hot indeed. I was very much thirsty. I asked him for a cool drink or a lemonade. But he offered me coconut water. At dinner he offered me raw roots and sugarcane. In my town 1 usually take delicious foods such as bread and jam; cheese, and different kinds of fruits. I didn’t like the food offered to me by him. At night I had to sleep on cold and hard ground. The life at the village is very different from that of the town. There is no glitter of lights. There are no buses, cars and even two wheelers. It appears very dull when compared to the city life. There was no ready food. I had to go to nearby farms in search of food. 1 felt the village life dreadful and unpleasant. I cannot accustom with the hardships of the village life system. So I came back to the town the very next day. And I never visited the village again in my life. I thought that the city, in which I live, is the heaven on this earth.

(Or)

I am a country mouse. I live in the countryside. On receiving an invitation from my cousin, the town mouse, I went to his town. His house was at the back of a kitchen cupboard. There he received me warmly. But my head began to ache because of the noise caused by ’ the traffic of cars, buses and lorries, running in the streets of the town. They also cause air-pollution. I was also surprised to see the lights even in the middle of the night. On my asking, my cousin replied that it was common in towns. I wanted to drink some water and eat raw food like the root and the sugar-cane. But my cousin offered me ice-cold orange juice to drink. He also offered me bread and jam, different kinds of fruit and slabs of chocolate. But I could not eat any in peace because he pushed me out through a hole when somebody was opening the cupboard door. On the whole, it was not a pleasant experience and I decided not to visit the town again.

Listening and Speaking

I. An old student of your school visits your school. Your teacher introduces her to your class like this. (Now the teacher has to read the following information.)

My dear students! Look, who is here! This is Kumari Nithya. I am very happy to introduce her to you. She was my student; I mean, a student of this school. You know, she is now working as a software engineer in a big company. When I remember Nithya, I see a pretty little girl with two plaits sitting in the first row eagerly waiting for a chance to speak. She would answer any question at the drop of a hat.
When I talked to others, she would become restless and went on saying ma’am, ma’am, thrusting her hand into air. No wonder she passed S.S.C. in first class and scored more than 550 marks. I hope you have seen her name in our H.M.’s room, haven’t you?
Going by her marks, don’t think she is just a bookworm. She did equally well in sports and games. She led our school kabaddi team to state level competitions. There are many other things that I would like to share with you, but I’m leaving them, especially the naughty things, for her to share with you.
Now Nithya will address you. Nithya …. !

Imagine that your eldest brother has come to your school. Introduce him to your class and your teachers.

Respected teachers ! My dear friends ! I think the person standing by my side is known to many of the teachers, here. This is Hanuman. I am very happy to introduce him to you. He is my eldest brother. He was a student of this school. He is, now, doing his engineering.
He is sharp right from the start. He has passed S.S.C. and scored more than 570 marks. I hope you have seen his name in our H.M.’s room, haven’t you? But don’t think, he is just a bookworm. He has done equally well in sports and games. If you want to know some more about him, you can talk to him. Thank you all, for giving me this opportunity.

The town-mouse offered him bread and jam, different kinds of fruit, slabs of chocolate and a huge piece of lovely cheese. The country mouse had to eat and drink what the town mouse had offered. Meanwhile, they had to run for safety and hide themselves as somebody entered the room and opened the cupboard. The country mouse was tired of doing this and did not like to be there. So, he took leave of his cousin and went back to his house in the country. Since then, they did not visit each other again.

Question 1.
Find out 12 ÷ 3 and 4 ÷ 7.
Solution:
12 ÷ 3
12 is divided by 3 means, we subtract 3 from 12 repeatedly till, we get zero i.e., we subtract 3 from 12 again and again till, we get zero.
12 – 3 = 9 once
9-3 = 6 twice
6-3 = 3 thrice
3-3 = 0 four times
So, 12-3 = 4

42 ÷ 7
42 is divided by 7 means, we subtract 7 from 42 repeatedly, i.e., we subtract 7 from 42 again and again till, we get zero a number less than 7.
42 – 7 = 35 once
35 – 7 = 28 twice
28 – 7 = 21 thrice
21-7 = 14 four times
14-7 = 7 five times
7 – 7 = 0 six times
i.e., we can subtract 7 from 42 for 6 times successively. ,
So, 42 ÷ 7 = 6.

AP Board 6th Class Maths Solutions Chapter 2 Whole Numbers InText Questions

Question 2.
What would 6 4-0 and 9 4- 0 be equal to?
Solution:
6 ÷ 0
6 is divided by 0 means, we subtract 0 from 6 repeatedly i.e., we subtract 0 from 6 again and agian from 6.
6 – 0 = 6 once
6 – 0 = 6 twice
6 – 0 = 6 thrice and ……………….
If we subtract zero from 6 successively we can’t get zero at any end.
So, 6 ÷ 0 is not a number that we can reach.
So, division of a whole number by 0 does not give a known number as answer, so it is not defined.
Similarly 9 ÷ 0 is not defined.
So, we can’t say whether they are equal or not.

Verify the following:
i) (5 × 6) × 2 = 5 × (6 × 2)
Solution:
L.H.S : (5 × 6) × 2 = 30 × 2 = 60
R.H.S : 5 × (6 × 2) = 5 × 12 = 60
∴ L.H.S = R.H.S
So (5 × 6) × 2 = 5 × (6 × 2)
∴ Multiplication of whole numbers is associative.

ii) (3 × 7) × 5 = 3 × ( 7 × 5 )
Solution:
L.H.S : (3 × 7) × 5 = 21 × 5 = 105
R.H.S : 3 × (7 × 5) = 3 × 35 = 105
∴ (3 × 7) × 5 = 3 × (7 × 5)

Use the commutative and associative properties to simplify the following:

i) 319 + 69 + 81
Solution:
319 + 69 + 81 = 319 +(81 + 69) (Commutative property)
= (319 + 81) + 69 (Associative property)
= 400 + 69 = 469

ii) 431 + 37 + 69 + 63
Solution:
431 + 37 + 69 + 63
= 431 + (37 + 69) + 63
= 431 + (69 + 37) + 63 (Commutative property)
= (431 + 69) + (37 + 63) (Associative property)
=(431 + 69) + 100
= 500+ 100 = 600

AP Board 6th Class Maths Solutions Chapter 2 Whole Numbers InText Questions

= 10 × 71
= 710

iv) 50 × 17 × 2
Solution:
50 × (17 × 2) = 50 × (2 × 17) (Commutative property)
= (50 × 2) × 17 (Associative property)
= 100 × 17 = 1700

Let’s Think (Page No. 22)

a) Is(8 ÷ 2) ÷ 4 = 8 ÷ (2 ÷ 4)?
Is there any associative property for division ?
Check if this property holds for subtraction of whole numbers too.
Solution:
a) (8 ÷ 2) ÷ 4 = (8 ÷ 2) ÷ 4
= 4 ÷ 4 = 1
8 ÷ (2 ÷4) = 8 ÷ \(\left(\frac{2}{4}\right)\)
= 8 – \(\frac{4}{2}\) = 8 × 2 = 16
So, (8 ÷ 2) ÷ 4 ≠ 8 ÷ (2 ÷ 4) .
Therefore, associative property does not holds in division.

b) Is (8 – 2) – 4 = 8 – (2 – 4) ?
Solution:
(8 – 2) – 4 = 6 – 4 .
= 2
8 – ( 2 – 4 ) = 8 – ( – 2)
= 8 + 2 = 10
So, (8 – 2) – 4 ≠ 8 – (2 – 4)
Therefore, associative property does not holds in subtraction,
i. e., whole numbers are not associative w.r.t. subtraction.
They are not equal.
So whole numbers do not satisfy Associative property w.r.t. Subtraction & Division.

A car is moving at a constant speed covers a distance of 180 km in 3 hours. Find the time taken by the car to cover a distance of 420 km at the same speed.
Answer:
Distance covered = 180 km
Time taken = 3 Hrs.
Distance to be covered = 420 km
Time required = ? = x (say)
Since the car is moving at a constant speed, we have
180 : 3 is as to 420 : x
180 : 3 :: 420 : x
Its a proportion.
So, product of extremes = Product of means
180 × x = 3 × 420

∴ Time required = 7 Hrs.
(OR)
Distance covered by a car in 3 hours = 180 km
Distance covered by a car in 1 hour = 180 ÷ 3
Time taken to cover 60 km distance = \(\frac{180}{3}\) = 60 km
Time taken to cover 420 km distance = 420 ÷ 60 = \(\frac{420}{60}\) = 7 hours

Question 5.
A truck requires 108 litres of diesel for covering a distance of 594 km. How much diesel will be required by the truck to cover a distance of 1650 km?
Answer:
108 : 594 :: x : 1650
So, 108 × 1650 = x × 594
∴ x = \(\frac{108 \times 1650}{\hline 594}\) = 300 litres
(OR)
Distance covered by truck with 108 litres diesel = 594 km
Distance covered by truck with 1 litre of diesel = \(\frac{594}{108}\) km
Diesel required to cover 1650 km distance = 1650 ÷ \(\frac{594}{108}\) = 1650 × \(\frac{108}{594}\)
Diesel required to cover 1650 km distance = 300 litres.
