Question

what is the two types of tissues

Answer 1

Plant tissue and Animal tissue.

Answer 2

$\huge\mathfrak\pink{Answer}$

There are two types of tissues :-

★ Meristematic Tissues

★ Permanent Tissues

❥Meristematic Tissues$\tt{\implies}$

1) In these tissues, cells are thin living and isodiametric. Their cell wall is formed of cellulose.

2) These are oval or rounded aur polygonal - shaped.

3) The cells are compactly arranged, so not having intercellular spaces.

4) The class contained dense cytoplasm with no or a few small size vacuoles. Their nuclie are prominent.

5) These are capable of division throughout life, so help in growth.

6) These are localized in certain reasons.

On the basis of their location, primary Meristematic tissues are of three types.

1) Apical Meristem

2) Intecalary Meristem

3) Lateral Meristem

★ Apical Meristem :-

It lies at the apices of root, stem and stem branches. It helps in longitudinal growth, called primary growth. Shoot apical Meristem is terminal in position and is is protected by leaf Primordia weil root apical Meristem is subterminal and is not protected by leaf primordia.

★ Intecalary Meristem:-

It lies below the base of internodes of stem of grasses. It helps in longitudinal or primary growth of plants by adding primary tissue.

★Lateral Meristem ( Cambium:-

It lies on the lateral sides of stem and root, and helps in increasing their diameter (girth) so helps in secondary growth e.g. Cambuim in the vascular bundles of dicot stems.

❥Permanent Tissues $\tt{\implies}$

1) In these tissues, cells are thin walled, living or dead, and mature.

2) These may be oval or rounded or polygonal or elongated fibre-like.

3) The cells have intercellular spaces.

4) These have vacuolated cytoplasm.

5) The cells have lost the power of division so do not help in growth.
