1.	Observe the illustration, which show plant hormones and their functions and complete the following table suitably.Plant hormonesFuctionsAuxin(a) ..................Abscisic acid(b) .................(c) ...............break down of stored food in the seedCytokinin(d) .......................(e) ...........helps in the ripening of fruits
Answer» a) Cell growth, cell elongation, fruit formation b) Controls the dormancy of embryo in the seeds, dropping to leaves and fruits wilting of leaves, flowering, etc. c) Gibberellins d) Promotes cell division cell growth e) Ethylene. Artifical Plant Hormones Auxins: Naphthelene Acetic Acid (NAA), Indol Butyric Acid (IBA), etc., are used for sprouting and the prevention of dropping of premature fruits. 2.4-D (2, 4-Dichloro phenoxy acetic acid) is used as a weedicide. Gibberellins: It is used for increasing fruit size in grapes and apple and also for preventing ripening of fruits to assist in marketing. Abscisic acid: As it accelerates the dropping of fruit, it is used for harvesting fruits at the same time. Ethylene: Ethylene is used for the flowering of pineapple plants at a time and for the ripening of tomato, lemon, orange, etc. Ethyphon, a chemical which is available in liquid form gets transformed into ethylene when used in rubber trees, and it increases the production of latex.
