Hey there,
(a) GA3 is also called as Gibberlins. It functions in the internode elongation. And when it is applied to the rice seedlings will lead to the total increase in the hight of the rice plant.
(b) Plant structures such as leaf and stem is formed because of the differentiation in dividing cells. But if it is stopped then these structures or organs will not be formed.
(c) The hormone named 'ethylene' helps in the ripening of the unriped fruits. And when ripened fruits gets mixed up with the unripened ones then the Ethylene gas produce will help to ripen the unriped fruits.
(d) Cytokinin helps the cells to divide , to grow etc. So, if we forget to add Cytokinin then these things will not occur.
Thanks!
