Answer:
Excretion in Plants
Elimination of toxic and waste products from the body is called excretion. Organisms like animals have an advanced and specialized system for excretion. But plants lack a well-developed excretory system like that in animals. They do not have special organs for excretion. Thus, excretion in plants is not so complex.
Excretory products
The cellular respiration, photosynthesis, and other metabolic reactions produce a lot of excretory products in plants. Carbon dioxide, excess water produced during respiration and nitrogenous compounds produced during protein metabolism are the major excretory products in plants.
Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration. Excretion of gaseous waste in plants takes place through stomatal pores on leaves. Oxygen released during photosynthesis is used for respiration while carbon dioxide released during respiration is used for photosynthesis.
Excess of water is also excreted from the plant body through the stomatal pores and from the surfaces of fruits and stems. The process of elimination of water is called transpiration.
Transpiration: Gaseous wastes and water are excreted through stomata, lenticels of the stem, and the outer surface of stems, fruits, etc.
Storing: Some organic wastes are stored in plant parts such as barks and leaves.
Diffusion: Aquatic plants excrete metabolic wastes through diffusion. Terrestrial plants excrete into the soil.
