Question

Name the common simple tissues of the plant body and write one function of each.

Answer 1

Simple tissues:

The tissues which are composed of similar permanent cells and aid in performing same or similar set of functions are known as simple tissues.

Types of simple tissues:

1. Parenchyma:
   1. The parenchyma has thin-walled cells, they are living and are soft in nature.
   2. Chlorenchyma is a type of parenchyma that contains chloroplasts.
   3. Photosynthesis is aided by these chlorenchyma tissues.
   4. In vegetables and fruits, some parenchymatous cells serve as starch storage chambers in stem and roots.
2. Collenchyma:
   1. They are characterised by live cells with irregular thick walls.
   2. This structural framework benefits from the flexibility of the cell walls, which also provides mechanical support.
3. Sclerenchyma:
   1. Sclerenchyma have thickened lignified walls in their cells, which give them strength and make them waterproof.
   2. It also aids in providing mechanical support to the plants.
