Plants retain the capacity for unlimited

Plants retain the capacity for unlimited growth throughout life because meristems keep producing new cells. This open form of growth keeps adding cell

Meristems are regions of active cell

Meristems are regions of active cell division. Root apical meristem and shoot apical meristem cause primary growth and increase length, while vascular

Growth occurs in three phases

Growth occurs in three phases: meristematic, elongation, and maturation. Meristematic cells are rich in protoplasm and have large nuclei; elongation i

In arithmetic growth

In arithmetic growth, after mitotic division, one daughter cell continues dividing while the other differentiates. It gives a linear growth pattern an
