What are the methods used by plants to get rid of excretory products

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. However, they get rid of their excretory products in the following ways:- • 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 like barks and leaves in the form of resins or gum. They later fall off. • Diffusion: Aquatic plants excrete metabolic wastes through diffusion. Terrestrial plants excrete into the soil.

The removal of the waste products of metabolism from living organisms is called as excretion. In plants, waste products are removed by diffusion. Plants, excrete oxygen, a product of photosynthesis. Plants get rid of water by transpiration. Waste products may be stored in vacuoles or may be stored in leaves which fall off. Resinsand gums are stored in xylem which are harmless to trees. When the leaves and bark are shed, the wastes are eliminated.

Hint: Plants need to excrete majorly carbon dioxide which is a gaseous excretory product of aerobic respiration. plants should excrete out the unwanted excretory products because retention of such substances may result in toxicity and even death of certain tissues. Complete answer: Plants excretes waste products by the following process- 1) Plants consume water, however, there exists some proportion not utilized. The excess water is excreted by the process known as transpiration. It is the process by which the water moves through a plant by evaporating from exposed parts for eg- leaves, stems and flowers. 2) Gaseous wastes such as carbon dioxide are eliminated through stomata. Carbon dioxide is a major product of aerobic respiration. 3) Removes the exudates like resins and gums especially in old xylem tissue. 4) Waste products are transported in the old leaves which are eliminated by the process of drooping or wilting. 5) The oxygen which is the end product of the photosynthesis gets eliminated through stomata. 6)Some of the excretory products are stored in vacuoles. 7) They also excrete some waste products into the soil around. 8) Some are also excreted by petals, fruits and seeds. Note: Resins and gums are some by-products of plant metabolism and often are a result of injury to the bark or wood of certain plants but can occur as normal metabolites. Gums and tannins extracted from the plants are of great industrial use for humans.

Methods used by plants to get rid of their excretory products- (i) Excess water is removed by transpiration. (ii) Some waste products are stored in vacuoles of cells. (iii) Some waste products may be stored in leaves which fall off. (iv) Many waste products like resins and gums are stored in non-functional xylem. (v) Oxygen removed through stomata. (vi) Plants excrete some waste materials into the soil around them.

Excretory products of plants: • Oxygen It is produced during • #CO_2# and Water These are produced during respiration. • Organic and Inorganic compound These are stored for different purposes and are removed when necessary. Organs used to excrete wastes • Leaves: Leaves are used to excrete wastes. Hence these are also known as excretophores. Plants store their organic and inorganic wastes mostly in leaves. Plants drop yellow leaves(these leaves have pigmented compounds and toxic materials) in the autumn. And eventually, plants get rid of these wastes. Water is also excreted through leaves by process of transpiration ans also water is stored for maintaining turgor. • Stems: Some trees deposit strange chemicals in the xylem of branches and trunks. These xylems then can't be used fro water transport. This takes place in ebony which is a very dark black wood present in the centre. Plant psychologists considers that strange chemicals as wast materials. • Roots: Some plant actively secrete waste compounds into the soil through their roots. • Vauoles: Plant cells have large large vacuoles which are used for the storage of both useful and waste substances. #Note:# Gases ilke #CO_2# and #O_2# are released through stomata.

Hint: Here, like human beings and animals excrete through their excretory systems, the plants too need to throw the unused or unwanted materials out from their body. We have to find the methods or ways in which they excrete their byproducts. Complete answer: There are three methods or ways through which the plants will remove their body wastes as mentioned below: A. Removal of solid waste materials through leaves and stems by the formation of gums and resins: Trees like Acacia, Dragon, Boswellia, Protium copal, and rubber plants excrete byproducts from stems and leaves cuts, nodes, and nodules in form of gums, resins, and aromatic oils. These gums and resins can be seen dropping out of the cuts, nodes, and nodules of the plant body. Rubber is a type of latex obtained from rubber tree leaves, nodes and stems. Turpentine is a type of oil obtained from Canada turpentine also known as Canada balsam, mastic is a plant resin obtained from a mastic tree known as Pistacia lentiscus. B. Removal of gaseous materials through stomata: Stomata are in the lower marginal surface of leaves of all plants. These porous openings help plants to exchange gases. During respiration, the plants and trees respire taking in CO$_2$ and giving out O$_2$ as a byproduct at day time. But at night, they give away CO$_2$ gas. Lenticels are pores on plants and trees are the internal tissues on the bark of trees. They provide a pathway for the direct exchange of gases. C. Removal of water through transpirat...
