Vacuoles, small pockets in the cytoplasm of a cell, stores masterials such as water, carbohydrates, protein, salt and other organic and inorganic substances. It plays an important role in digestion and excretion of cellular waste and part of the cell excretion process.
lysosome are the trash colectors
It is the vesicle. The vesicle A vesicle is a small, spherical compartment that is separated from the cytosol by at least one lipid bilayer. It contains digestive enzymes. Lysosomes are actually circular vesicles.
Excretion in animals: Many unicellular organisms like Amoeba throw out their wastes by diffusion from their body surface. Protozoan’s have no organs for excretion. As they live in an aquatic habitat, their wastes are eliminated by diffusion through the plasma membrane.
