Explanation:
Plants are made up of mainly two different tissues. They are :
1. Meristematic tissue
2. Permanent tissue
1. Meristematic tissues: These type of tissues are located at specific locations and divide continously to add new cells to the plant body.
2. Permanent tissue: These tissues are derived from the meristematic tissues, but have lost their ability to divide and attained their different forms. It includes simple and complex tissues.
Simple tissues are those which are structurally and funcutionally similar. These are of three types:
a. Parenchyma : They act as storage for food and water.
b. Collenchyma: They are living mechanical tissues owing to their supportive funcutions.
c. Schlerenchyma : It imparts hardness to the plant parts and gives mechanical support to them.
