Question

define meristematic tissue and their parts

Answer 1

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. As new cells are added by repeated mitotic divisions of the initial cells, the derivatives are pushed farther away from the zone of active division. They stretch, enlarge and differentiateinto other types of tissues as they mature. Meristematic cells are generally small and cuboidal with large nuclei, small vacuoles, and thin walls.

They are divided into :-

• Apical - It is present in the growing tips of stems and roots . and helps in elongation of stem. It is involved in the primary growth of plant

• Intercalary - It is present at the base of leaf and increase length of leaf.
