DENDROLOGY

Detailed explanation-1: -The aerial parts of the plant are generated by groups of rapidly dividing cells called shoot apical meristems.

Detailed explanation-2: -You’ll recall that the apical meristem is the site of cell division and new cell production at the tips of the plant stems and roots. The cells that make up the meristem are undergoing mitotic cell division to produce more cells. These new cells result in growth and development of plant tissues.

Detailed explanation-3: -Intercalary meristem Intercalary meristems are capable of cell division, and they allow for rapid growth and regrowth of many monocots. Intercalary meristems at the nodes of bamboo allow for rapid stem elongation, while those at the base of most grass leaf blades allow damaged leaves to rapidly regrow.
