        Asexual reproduction occurs when four nonmotile
        daughter cells are released from the protoplast
        of the parent cell. The processes of sexual
        reproduction are largely unknown.
         
        Chlorella is
        often confused with Chlorococcum based on morphology.
        However, Chlorococcum reproduces by releasing biflagellated
        zoospores,
        has chloroplasts that cover most of the cell
        wall, and is found in soil or on wood or rocks.
