A food vacuole is a membrane-enclosed cell vacuole with a digestive function, containing material taken up in by the process of phagocytosis. These are found in amoeba, protozoa, paramecium. In protozoa, whatever the mode of heterotrophic nutrition or diet, the food material is enclosed in food vacuoles, which are bounded by cell membrane. Digestive enzymes are poured into the newly formed vacuole from the surrounding cytoplasm.
EXCRETION IN AMOEBA. Amoeba is a unicellular organism found in fresh water. In amoeba carbon dioxide and ammonia are the main waster materials. These waste materials are excreted out by the process of diffusion through general body surface. In amoeba, contractile vacuoles also play some role in the removal of waste materials. The waste materials present in the cytoplasm of amoeba enters the contractile vacuole.
