Question

definition of:


apical meristem
intercalary meristem
lateral meristem



according to class-9. ​

Answer 1

Explanation:

apical meristem

Apical meristem, region of cells capable of division and growth in the root and shoot tips in plants.

intercalary meristem

An intercalary meristem is a primary meristematic tissue that helps a plant or tree to grow vertically by adding to its length.

lateral meristem

The lateral meristem is a type of meristem that occurs at the lateral areas of the plant.

Answer 2

Answer:

1. The apical meristematic tissue is a tissue found in the plant which is responsible for plant growth and found in the root tips as well as the tips of new shoots and leaves. One of three types of meristems, or tissue that can divide into various cell types, is the apical meristem.
2. The meristematic tissues that are present at the base of internodes of stem and petioles of leaves are known as Intercalary meristem. The function of these tissues is to promote the growth of the plants by elongating the nodes and internodes present at the leaves and stems
3. Lateral meristems are known as secondary meristems because they are responsible for secondary growth, or increase in stem girth and thickness. Meristems form anew from other cells in injured tissues and are responsible for wound healing.
