Explain the stages of growth in plants.

(N/A) The growth of a plant is a complex process that occurs in three main stages:
$1$. $Meristematic$ $phase$: This stage occurs in the root and shoot apices. Cells in this region are constantly dividing by mitosis. These cells are rich in protoplasm and possess large, conspicuous nuclei. The cell walls are primary, thin, and cellulosic with abundant plasmodesmatal connections.
$2$. $Elongation$ $phase$: This stage occurs just proximal to the meristematic zone. The cells undergo significant enlargement, which is responsible for the increased length of the organ. This phase is characterized by increased vacuolation, cell enlargement, and new cell wall deposition.
$3$. $Maturation$ $phase$: This stage occurs further away from the apex. The cells attain their maximal size in terms of wall thickening and protoplasmic modifications. The cells differentiate to perform specific functions, becoming mature tissues.
