          \n
        1. Insects like butterflies, honeybees, bumble bees, humming birds, bats, ants visit the flowers in search of nectar.<\/li>\n
        2. When insects come in contact with a flower, the pollen grains stick to their legs and wings.<\/li>\n
        3. When insects visit another flower, the pollen fall on its slimy stigma.<\/li>\n
        4. Thus they help in pollination.<\/li>\n<\/ol>\n

          Question 9.

          \nAnswer:<\/p>\n

            \n
          1. The pollen grains which fall on the stigma of a flower germinates.<\/li>\n
          2. A pollen tube is formed from the pollen grains.<\/li>\n
          3. The pollen tube travels from stigma to the ovules in the ovary.<\/li>\n
          4. Fertilization and zygote formation occur in ovary.<\/li>\n
          5. The zygote develops into an embryo.<\/li>\n<\/ol>\n

            Question 10.
            \nWhat changes will come in the flower after fertilization?
            \nAnswer:<\/p>\n

              \n
            1. After fertilization the ovary ripens and turns into fruit.<\/li>\n
            2. The remaining floral parts will fall off.<\/li>\n
            3. The ovules become the seeds.<\/li>\n<\/ol>\n

                  \n
                1. Layering is done with branches nearer to the ground.<\/li>\n
                2. Remove the bark of the stem at one place.<\/li>\n
                3. Bend the branch into the ground and cover it with soil.<\/li>\n
                4. Within one month roots will develop from that branch.<\/li>\n
                5. Separate it from the mother plant and plant it where ever you want.<\/li>\n

                  \nAnswer:
                  \nGrafting is a technique where two plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion, while the lower part is called the stock.

                  Procedure:<\/p>\n

                    \n
                  1. Remove the bark of the Stock and Scion plants in such a way that removed portions face each other.<\/li>\n
                  2. The parts where bark is removed are joined tightly with the help of a jute twine.<\/li>\n
                  3. Wrap and tie with a polythene paper.<\/li>\n
                  4. After a month, cut the upper part of Stock and lower part in Scion.<\/li>\n
                  5. Within an another month the Scion attaches to the Stock and grows.<\/li>\n

                    Question 4.
                    \nDescribe the structure of a flower.
                    \nAnswer:
                    \nFlower is the sexual part of a plant. The green part which connects the flower to stem is called the stalk. The stalk bears a slightly swollen head called Thalamus.<\/p>\n

                    Over the thalamus floral parts are arranged in four whorls.<\/p>\n

                    Calyx:
                    \nThe green cup shaped leaf like, fused structures that covers the internal parts are Sepals. They are collectively called as Calyx. (Whorl 1)<\/p>\n

                    Corolla:
                    \nThe white or brightly coloured structures are called Petals. They are collec\u00actively called as Corolla. (Whorl 2) .<\/p>\n

                    Androecium:
                    \nThe soft elongated structures attached to the petals are called Stamens. All the stamens are collectively called Androecium (Whorl 3). This is the male reproductive part of the flower. Each stamen has a swollen structure at the top called Anther.<\/p>\n

                    Gynoecium:
                    \nA bulged structure seated on the thalamus is called Ovary which continues into a fine tube like structure Style with a slimy bead like tip called Stigma. These are collectively called the pistil Gynoecium (Whorl 4). This is the female reproductive part of the flower’

                      \na) Birds like Bulbuls, Mynahs, crows eat the outer fleshy part gets digested in the food canal and the seed coats of them become tender.
                      \nb) They are then dispersed to other places as bird droppings.<\/li>\n
