Write a short note on: Development.

(N/A) Development is a term that includes all changes that an organism undergoes during its life cycle,from the germination of the seed to senescence.
The sequence of processes that constitute the development of a cell in higher plants is represented as follows: Meristematic cell $\rightarrow$ Plasmatic growth $\rightarrow$ Expansion (Elongation) $\rightarrow$ Differentiation $\rightarrow$ Maturation $\rightarrow$ Mature cell $\rightarrow$ Senescence $\rightarrow$ Death.
This process is also applicable to tissues and organs.
In broad terms,development is the sum total of both growth and differentiation in plants.
The developmental process of growth and differentiation is controlled by several intrinsic and extrinsic factors:
$(i)$ Intrinsic factors: These include both intracellular (genetic) or intercellular factors (such as plant growth regulators).
$(ii)$ Extrinsic factors: These include light,temperature,water,oxygen,nutrition,etc.
