Question

नेम द थ्री types of meristematic tissues and write the location and functions of each​

Answer 1

Answer:

There are three types of meristmatic tissues :

1. Lateral Meristem.

LOCATION:

These are situated at the growing tip of roots and stems, i.e. the shoot apex and the root apex. Apical meristems are also found at the apices of the leaves.

FUNCTION:

It brings about the elongation of the root and stem. It results in an increase in the height of the plant, which is called primary growth.

2. Apical Meristem.

LOCATION:

These are found beneath the bark (called cork cambium) and in vascular bundles of dicot roots and stems (called vascular cambium). They occur in thin layers. Cambium is the region which is responsible for growth in thickness.

FUNCTION:

It causes the organ (stem or root) to increase in diameter and girth. This is called secondary growth.

3. Intercalary Meristem.

LOCATION:

They are located at the base of leaves or internode, eg, stems of grasses and other monocots. Such tissues also occur below the nodes (eg, mint).

FUNCTION:

It produces an increase in the length of an organ such as leaves and internodes.
