Explanation: 

Detailed explanation-1: -“Meristematic tissue is the plant tissue that has the ability to divide actively throughout its life.”

Detailed explanation-2: -Meristematic tissues, or simply meristems, are tissues in which the cells remain forever young and divide actively throughout the life of the plant. When a meristematic cell divides in two, the new cell that remains in the meristem is called an initial, the other the derivative.

Detailed explanation-3: -Meristematic tissues are responsible for plant growth. They are present at the tips of roots, stem and branches. The cells present in these tissues constantly divide to produce new cells. This leads to an increase in the height and girth of plants.

Detailed explanation-4: -There are three primary meristems: the protoderm, which will become the epidermis; the ground meristem, which will form the ground tissues comprising parenchyma, collenchyma, and sclerenchyma cells; and the procambium, which will become the vascular tissues (xylem and phloem).
