EXCRETION IN PLANTS AND ITS ECONOMIC IMPORTANCE

Excretion is the elimination of waste products of cell metabolism from the body.

These waste merchandise can also be poisonous (toxic) to the physique if saved in excess.
Examples of these excretory waste merchandise consist of water and salt. Nitrogenous compounds like ammonia, urea, uric acid, and carbon dioxide from respiration.

Osmoregulation is the technique by means of which the osmotic stress of the blood and tissue fluids is stored constant.

Excretory wastes of plants are minimal and these do not have a distinct excretory system. Waste products of metabolism in vegetation are normally carbon dioxide, water, oxygen, resins, tannins, acids, latex, mucilage, alkaloids crystals of salts, oil, gum, anthocyanin, glycosides (compounds containing sugar) e.t.c.

Water, carbon dioxide and oxygen are eradicated through diffusion through the stomata and lenticel. Tannins, crystals anthocyanin, glycosides, and alkaloids are transformed into insoluble compound and deposited in useless tissue like the bark of leaves and petals.

In some plants, secretory merchandise like latex, resins, gums and mucilage are secreted with the aid of one of a kind cells or glands in plant body. They are saved in distinct canals or duct and ooze out of the plant when some phase of it is damaged, but are not often excreted.

• Gums are used as adhesives in many manufacturing industries.

• Resins are used for transient closure of wound, as disinfectant.

• Tannings are used for making ink, used in tanning of hides into leather.

• Anthocyanin are used for demise of materials.

• Camphor are used for cosmetics and manufacturing of medicine

• Ginger is used as spices for beverages.

• Eucalyptus is used in manufacturing of perfumes.

• Quinine from leaves of neem tree is used as anti-malaria drug.

• Morphine is used as narcotics.

• Cocaine located in cocoa leaves are used as stimulants.

• Nicotin in tobacco leaves act as stimulants
