Excretory system is defined as the process by which the waste materials are eliminated from the body of a plant, animals or human bodies. The excretory system of plants is somewhat different from animals and is quite simple. Plants can excrete their products such as-
1) Oxygen by absorbing carbon dioxide
2) Releasing water in the form of water vapor due to the evapotranspiration process
3) Releasing carbon dioxide at night
<u>The plant bodies are so simple that it does not require any organs to remove its waste materials. So they are easily eliminated from their bodies.</u>
