Excretory System in Plants

Plants as living organisms produce metabolic wastesMetabolic wastes are the substances leftover from metabolic processes (like cellular respiration) which are not absorbed by the organism and hence they should be excreted. Metabolic wastes can be categorized into... More such as carbon dioxide, water, and oxygen. These metabolic wastes can be retained and recycled in plants. The by-products of respiration i.e. carbon dioxide and water are retained and used for photosynthesisPhotosynthesis is the process by which green plants, and some algae and bacteria, convert the energy of sunlight into chemical energy. This energy is then used to synthesize carbohydrates such as... More. Oxygen a by-product of photosynthesis is used by the plant for respiration.
