1.	Explain the process of excretion in plants?
Answer» 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.The major waste substances produced by plants are oxygen, carbon dioxide and water. They can get rid of excess water by transpiration. Many of the toxic waste products are stored within dead permanent tissue which are removed periodically. Waste products are stored in leaves which may fall off. Some waste products such as latex, gum, resins are stored in old Xylem.Alkaloids are a group of toxic waste products. But some of these are useful to us. Quinine and morphine are medicines derived from alkaloids stored in Cinchona bark and opium poppy flowers respectively. Caffeine found in coffee seeds and nicotine in tobacco leaves is also alkaloids.
