Question

epidermis is important for the plants give reason​

Answer 1

Answer:

1. It covers the body from outside and protects them from pathogen attack and atmospheric changes.  

2. It bears stomata which are involved in gaseous exchange (oxygen, carbon dioxide) with the atmosphere. It also has lenticels on the woody stem for gaseous exchange.  

3. The stomata present on leaves are also involved in transpiration (water evaporation from plant body). Stomata are guarded by guard cells, which close and open the stomata as per requirement. Therefore, epidermis bearing stomata also checks water loss from the plant body.  

4. The epidermis is protected by cuticle at some parts of the tree and it helps to stop water loss by evaporation.
