6 phases

Explanation:
Detailed explanation-1: -There are three phases of growth – meristematic, elongation and maturation.
Detailed explanation-2: -Interphase is known as the period of growth.
Detailed explanation-3: -Plants growth results from the coordinated interaction of mitotic cell cycle and cell expansion. As in animals, the plant cell cycle consists of four distinct phases: G1 (postmitotic interphase), S (DNA synthesis phase), G2 (premitotic interphase), and M (mitosis/cytokinesis).
Detailed explanation-4: -So, when the plant growth is plotted in a particular plane, it gives rise to an S-shaped curve known as the sigmoid curve of plant growth. There are three phases of the sigmoidal growth of plant growth. Those are: Initial exponential phase.
