Question

Classify meristems on the basis of their position in plant body and describe the different types.

Answer 1

$\huge \text {Answer -}$

$\large \textbf {\underline {Meristematic \: tissue}}$

-Cells of Meristems divide continuously and help in increasing the length and girth of the plant.

-Meristematic tissues are growth tissues and are found in the growing region of the plant.

-According to their position in the plant, Meristems are apical, lateral, and intercalary.

$\large \textbf {Functions-}$

1)Meristmatic tissue act as a parent tissue from which other tissue develops.

2)These tissue take part in growth by formation of new cells.

3)With the help of Meristems, plants continue to produce new leaves, branches of stem and root, flowers, fruits, and root hairs.

$\large \textbf {\underline {Apical \: Meristems}}$

-These are situated at the growing tip of stem and roots, i.e., at shoot apex and root apex.

$\large \textbf {Functions -}$ 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.

$\large \textbf {\underline {Lateral \: Meristems}}$

-These are found beneath the bark (called cork cambium) and in vascular bundle of dicot roots and stems (called vascular bundle).

$\large \textbf {Function -}$ It causes the organ to increase in diameter and girth. This is called secondary growth.

$\large \textbf {\underline {Intercalary \: Meristems}}$

-They are located at the base of leaves or internodes.

$\large \textbf {Functions -}$ It produces an increase in the length of an organ such as leaves and internodes.
