Explain the Process of Excretion in Plants<\/span><\/h2>\n
Excretion in Plants<\/strong><\/span> \nPlants do not produce nitrogeneous wastes like urea and uric acid because extra amino acids and nucleotides are not formed. They produce other types of waste products, called secondary metabolites, e.g., alkaloids, tannins, aromatic oils.<\/p>\n
The main products excreted by plants are:<\/strong><\/span><\/p>\n\n
Carbon dioxide and oxygen<\/strong> Carbon dioxide is formed as a result of respiration. Oxygen is formed as a result of photosynthesis.<\/li>\n
Excess water<\/strong> It is excreted through stomata and the process is called transpiration.<\/li>\n
Excessive salts<\/strong> If there is a high level of salts present in water or in the soil, these usually get deposited in plants as crystals.<\/li>\n
Nitrogenous Waste Products.<\/strong> They are byproducts of general metabolism. The common ones are alkaloids, e.g., quinine, morphine, atropine.<\/li>\n
Organic Acids.<\/strong> They are metabolic intermediates. Some of them are without any other use. Rather on accumulation they may prove toxic, e<\/em>.g<\/em>., oxalic acid.<\/li>\n
Tannins.<\/strong> They are complex aromatic compounds which are formed as secondary metabolites.<\/li>\n
Latex.<\/strong> It is an emulsion of varied composition which is exereted by special tubular cells called laticifers.<\/li>\n
Resins. <\/strong>They are oxidation products of aromatic oils.<\/li>\n
Gums.<\/strong> They are degradation products of cell wall.<\/li>\n<\/ol>\n
