It produces an increase in the length of an organ such as leave and internodes. They are located at the base of leaves or internal, e.g., stems of grass and other monocots. Such tissue also occur below the nodes (mint).

$\bold\purple{\underline{\underline{\mathtt\pink{Apical\:\:Meristem-}}}}$

it brings about the elongation of the roots and stem. It results in an increase in the height of the plant, which is called primary growth. These are situated at the growing tip of stems and roots, i.e., at shoot apex and root apex. Apical meristem are also found at apices of the leaves.

$\bold\purple{\underline{\underline{\mathtt\pink{Additional\:\: Information-}}}}$

• Cells of meristems divide continuously and help in increasing the length and girth of the plant.

• The cells of meristematic tissue are similar in structure and have thin cellulose cell walls.

• The meristematic cell may be spherical, oval, polygonal or rectangular in shape.

• The meristematic cells are compactly arranged and do not contain any intercellular space between them.

• Each meristematic cell contains dense or abudant cytoplasm and a single large nucleus.

• The meristematic cell contain few vacuole or no vacuoles at all.
