Professor PC Thomas Classes · Answer

(d) : Development is the sequence of events that occur in the life history of a plant which includes seed germination, growth, differentiation, maturation, flowering, seed formation and senescence. The process of development is considered as the sum of growth and differentiation controlled by several intrinsic factors (including genetic and hormonal) and extrinsic factors (including light, temperature, water, oxygen, nutrients, etc).
