a space or cavity in the protoplasm of a cell.
contractile vacuole a small fluid-filled cavity in the protoplasm of certain unicellular organisms. It gradually increases in size and then collapses; its function is thought to be respiratory and excretory.

vacuole

A small, clear region in the CYTOPLASM of a cell, sometimes surrounded by a membrane. Vacuoles may be used to store cell products or may serve an excretory function.

vacuole

a membrane-bound compartment within the cytoplasm of a cell, containing cell sap, for example water, air, food. The central vacuole in the plant cell is surrounded by the TONOPLAST. see CONTRACTILE VACUOLE.
