Name the various types of plant tissues and state their functions.

Plant tissues are divided into two types:

1. Meristematic tissue — They divide rapidly and continuously as a result of which the plant gains height. Based on their location in the plant body, they are of two types:
   1. Apical meristematic tissue — It is present at the root and shoot tips. It increases the length of the plant.
   2. Lateral meristematic tissue — This meristematic tissue is present on the lateral sides of the root and stem. This tissue is called the lateral meristematic tissue or cambium. It is responsible for the increase in the thickness of the roots and stem.
2. Permanent tissue — These tissues perform specific functions. They are classified into two types:
   1. Simple permanent tissue — This tissue provides support and protection to plants and is further classified into two types:
      1. Protective tissue — Epidermis and Cork are two protective tissues in plants.
      2. Supporting tissue — Supporting tissue comprises of Parenchyma, Collenchyma and Sclerenchyma.
   2. Complex permanent tissue — The main function of these tissues is to transport water and food materials. Therefore, these tissues are also called conducting tissues. It comprises of Xylem and Phloem.
