Explain the phases of growth in plants.

(N/A) The period of growth is generally divided into three phases: meristematic,elongation,and maturation.
$1$. Meristematic Phase: The cells in the root and shoot apices are constantly dividing. These cells are rich in protoplasm and possess large,conspicuous nuclei. Their cell walls are primary,thin,and cellulosic with abundant plasmodesmatal connections.
$2$. Elongation Phase: Cells proximal to the meristematic zone represent the phase of elongation. This phase is characterized by increased vacuolation,cell enlargement,and new cell wall deposition.
$3$. Maturation Phase: Further away from the apex,cells reach their maximal size in terms of wall thickening and protoplasmic modifications. This is the maturation phase,where cells differentiate to perform specific functions.
