Excretion in Plants
Excretion in Plants:
Compared to animals, plants do not have a well-developed excretory system to remove nitrogenous waste materials. This is because of the differences in their physiology. Therefore, plants use different strategies for excretion.
The gaseous waste materials produced during respiration (carbon dioxide) and photosynthesis (oxygen) diffuse out through stomata in the leaves and through lenticels in other parts of the plant. Excess water evaporates mostly from stomata and also from the outer surface of the stem, fruits, etc., throughout the day. This process of getting rid of excess water is called transpiration.
The waste products, like oxygen, carbon dioxide and water, are the raw materials for other cellular reactions. The excess of carbon dioxide and water are used up in this way. The only major gaseous excretory product of plants is oxygen.
