Question 1.
\nExplain in brief the scope of Botany in relation to agriculture, horticulture and medicine.
\nAnswer:<\/p>\n

    \n
  1. The problems like decreasing resources and increasing population could be solved by enhancing crop yield through Green Revolution and.also by developing disease* pest resistance crops by utilizing the principles of Biotechnology.<\/li>\n
  2. Progress in Agriculture, Forestry horticulture is possible through hybridization experiments and Genetic Engineering technology.<\/li>\n
  3. New plant breeding techniques are useful to develop hybrid varieties in crop plants like Rice, Wheat, Maize, Sugarcane etc.<\/li>\n
  4. Phytopathology is helpful in the prevention and eradication of several plant diseases.<\/li>\n
  5. Knowledge on the role of plant hormones in plant growth and development is significant to improve Agriculture and Horticulture through herbicidal control of weed, breaking of seed dormancy etc., Experiments in tissue and organ culture is possible to produce large number of plants in the laboratory within a short duration.<\/li>\n
  6. Several industries could be developed based on Botany.<\/li>\n
  7. Studies in Medicinal plants like Arnica, Cinchona, Neem, Datura, Rauwolfia, Ocimum are also important to explore them for human health care.<\/li>\n
