Question

what is meristematic tissue and characteristics

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 differentiate into other types of tissues as they mature. Meristematic cells are generally small and cuboidal with large nuclei, small vacuoles, and thin walls.

Characteristics of meristematic tissue

(Greek word; meristos- means “divisible”)

Meristematic tissue is a group of cells that has power of continuous division.

Cells are immature and young

Meristematic tissue is commonly called as meristems.

Shape of cell: each cell is oval, rounded, polygonal or rectangular

Size: small

Intercellular space: Absent

Cell wall: thin walled made up of cellulose

Nucleus: single large and prominent

Reserved food: cell do not store food

Cell division: high capacity and continuous

Metabolic activity: very high

 

Answer 2

meristematic tissue found in plants are the ones that continuously divide
it's characteristics include :-
it has a thin cell wall
no secondary cell wall
no intercellular spaces
a large and distinct nucleus with nucleoid
continuously dividing
no vacuoles
etc.
