The contractile vacuole is an organelle found in paramecia, a group of unicellular organisms. Contractile vacuoles pump out fresh water that accumulates in the organisms by osmosis. If the contractile vacuoles did not perform this function, could the paramecia maintain homeostasis?
They would burst if they do not have contractile vacoule to help them maintain homeostasis i.e. pump out excess fresh water that accumulates in them by osmosis.
