Cells containing membrane-bound organelles, such as chloroplasts and nuclei.
-
Cells ovoid, dividing with an oblique division plane.
Coccomyxa/Pseudococcomyxa
-
Ovoid cells; division plane not oblique; chloroplast usually bilobed.
Elliptochloris
-
Cells small and spherical when young, large and maybe elongated when old, with thickened walls, containing numerous small discoidal yellow-green chloroplasts.
Botrydiopsis
-
Cells small and spherical, with one cup-shaped or a few plate-like grass green chloroplasts.
Chlorella - like unicells
-
Cells always spherical, but varying greatly in size, and containing numerous discoidal chloroplasts.
Bracteacoccus
-
Cells ovoid to lemon-shaped, may occur singly but may also be found in small groups inside a large, inflated, remnant mother cell wall.
Oocystis
-
Cells large, cylindrical with rounded ends, two star-shaped axial chloroplasts, one at each end of the cell, separated by a clear area (in which the nucleus may be visible).
Cylindrocystis
-
Cells spherical to ovoid to slightly irregular, each containing a single grass green band-shaped chloroplast with a prominent pyrenoid; pyrenoid is surrounded by starch grains; cells divide simply into 2 without sporangia.
