Explain Cytoplasmic Vacuoles

Figure illustrates the structure of vacuoles. These are the voids in the cytoplasm which store small molecules such as water, ions, sucrose and amino acids. They appear as blobs and perform a variety of functions such as concentrating mineral salts in plant cells or excrete materials and digest food nutrients. Some primitive prokaryotes float in water because of air present in the vacuoles called as 'air vacuoles'.
