Classification of Meristematic Tissue

Functions of Meristematic Tissue:

1. Meristems are actively dividing tissues of the plant.

2. They are responsible for primary (elongation) and secondary (thickness) growth of the plant.

3. All new organs and their growth occur by the division of meristematic tissue.

4. Secondary tissues such as, wood, cork are also formed due to activity of meristematic tissue.

Answer 2

Answer:

characteristics of meristematic tissues are : -

Explanation:

i. The meristematic cells are living cells.

ii. These consists of small, thin-walled cells.

iii. In shape, the cells may be spherical, oval, polygonal or rectangular.

iv. They are compactly arranged and lack intercellular spaces.

v. The cells contain a prominent nucleus and

dense cytoplasm. Vacuoles are generally absent.

FUNCTION : -

# To form new cells and bring about increase in length and grith of the plant body
