Contractile vacuole is an organelle will be found in chlorella but not the paramecium.
The lowest metazoans, such as sponges and hydras, and freshwater protozoa have regulating organelles called contractile vacuoles that gather extra fluid from the protoplasm and occasionally release it into the surrounding media. Wastes containing nitrogen may also be excreted.
The contractile vacuole (CV) complex is an osmoregulatory organelle found in free-living amoebae and protozoa that regulates intracellular water balance by storing and excreting excess water, enabling cells to survive under hypotonic stress, like that found in pond water.
