Question

explain merismatic tissue​

Answer 1

Meristematic Tissue

→ These are simple living tissues having thin walled compactly arranged immature cells which are capable of division and formation of new cells.

Features of Meristematic tissues:

→ Thin primary cell wall (cellulosic).

→ Intercellular spaces are absent (compact tissue).

→ Generally vacuoles are absent, dense cytoplasm & prominent nuclei are present.

→ Large numbers of cell organelles are present.

→ Active metabolic state, stored food is absent.

→ Actively dividing cells are present in growing regions of plants, example: root & shoot tips.

Classification of Meristematic Tissues on the Basis of Origin

• Primary (Promeristem)

→ Derived directly from the meristems of embryo.

→ They consist of cells derived from primary meristem.

→ They add to primary growth of plants.

• Secondary Meristematic Tissues

→ Formed by permanent tissues.

→ These are having cells derived from primary permanent tissue.

→ They usually add to the diameter of plants.
