 | | All members of Division Cyanophyta, the "blue-green algae", are prokaryotic cells with no organized nucleus and no mitochondria or chloroplasts. |
 | | Members of the Division Pyrrophyta, also known as dinoflagellates, contain chlorophylls a and c, and may be armored with plates known as theca. |
