Cell of symmetrical structure, with a rigid silica case, usually intricately ornamented. May be variously symmetrical; attached, motile, or forming chains or colonies. | Diatoms |
|||
Cell of symmetrical structure, apparently composed of two identical halves, sometimes divided by a constriction, with chloroplast(s): no silica case. | Desmids
|
|||
Cell not regular, not composed of two halves | key under construction | |||
Cell motile by means of flagellae (but may lose them, or be inactive) |

(not many cyanobacterial species are single-celled) | |||
Cell spherical to club-shaped, attached. In older cells may form a short filament with a spherical spore at the tip, enclosed in a thin sheath. | Chamaesiphon | |||
Cell short-cylindrical or constricted in the middle, no sheath | Synechococcus | |||
