Zoochlorelle
Zoochlorella are green algae ( Chlorophyta ) from the (probably polyphyletic ) genus Chlorella , which are found as endosymbionts in ciliate animals such. B. Paramecium bursaria , amoebas and the cells of various multicellular animals such. B. those of the freshwater polyp Hydra viridissima and the giant green anemone live. The algae deliver assimilates to their host (30-40% of their production) and, in addition to the protection provided by the larger organism, receive a. Nitrogen compounds that would otherwise be excreted. Together with the equally living zooxanthellae , they provided the inspiration for the endosymbiont theory . In a broader sense, other green algae that live in animals or protozoa are also referred to as zoochlorella, for example the Tetraselmis convolutae living in the flatworm Convoluta roscoffensis .
