Hint:Humans and animals excrete their waste products by urine and feces. As plants are also living beings and they have their waste product, they excrete that waste in many ways. One of their sources of excreting is stomata.
Complete answer: Excretion is the process by which waste products of metabolism and other non-useful materials are eliminated from an organism. Invertebrates this is primarily carried out by the kidneys and through the skin. Unlike a human, plants do not have any special organ meant for the only excretion. Plants excrete excess carbon dioxide and oxygen. Carbon dioxide is a waste product of aerobic respiration in plant cells. Oxygen is a waste product of photosynthesis. It also excretes out nitrogenous waste from the body. The process of excretion occurs in many ways such as:-
Excess of ${CO_2}$ or ${O_2}$ in the leaves exit through stomata to the air. They are also brought by phloem and xylem from different parts in the plant body to the place where there are stomata present to exit it to the air.
Excretion also occurs by Guttation and Transpiration. Guttation is the method of secretion of water and its solutes by hydathodes found in the leaf's epidermis of some plants in the hummed environment. Transpiration is the process in which Water evaporates from the surface of leaves through the stomata.
Excretion of Nitrogenous Compounds occurs when Terrestrial plants convert excess amino acids into uric acid and Keto acids by deamination and deposit as crystals in the leaves and these crystals down the leaves. And in Aquatic plants, the excess of amino acids are converted to ammonia and keto acids; ammonia exists outside the plant through stomata, which is then released into the atmosphere.
Excretion of excess salts occurs by salts glands. These glands are present in halophytes.
Note: The cellular respiration, photosynthesis, and other metabolic reactions produce a lot of excretory products. Carbon-dioxide during Photosynthesis and water produced during Transpiration, nitrogenous waste is the major excretory products released from plants.
