Explain Excretion in Plants


The removal of toxic, waste metabolic products from the body is known as excretion. All plants and animals produce harmful substances due to a number of metabolic activities occurring in their bodies.

Excretion in Plants:

The major characteristics of plant excretion are listed below:

1. In comparison to animals, excretion in plants is more simple.

2. Plants are metabolically less active, so little amount of waste products are formed in them.

3. Excretorty products formed by the plants are less toxic.

4. As plants mostly use carbohydrates in their metabolic processes, excretory products other than carbon dioxide are produced in very small amounts.

5. Plants use some of the metabolic wastes for the synthesis of cellular materials. For example, ammonia produced during the catabolism of proteins is used for the synthesis of amino acids.

6. Most of the excretory products remain stored in parts of the plant body as insoluble crystals or as colloidal particles.

7. Due to the absence of well-developed excretory organs, plants can’t eliminate excretory substances as easiliy as the animalls.
