Divisions of Algae

Glaucophyta.

The glaucophytes are unusual unicells in which the plastids are recent endosymbionts.

Cryptophyta.

The cryptomonads are unicells with phycobiliprotein pigments like the red algae, but the pigments are located in a different position within the chloroplast.

Haptophyta.

The haptophytes are distinguished by the haptonema, an anterior filament that sometimes serves to attach the unicells to a substrate or to catch prey. The haptophytes include the coccolithophorids, the scales of which formed the white cliffs of Dover on the coast of England.

Dinophyta (Or Pyrrhophyta).

The dinoflagellates provide a good example of the problems in classifying algae, as many species do not have chloroplasts and, thus, live heterotrophically. As discussed above, some species are notorious for causing HABs, including red tides.

Euglenophyta.

The euglenoids are motile unicells often found in organically enriched waters; like the dinoflagellates, some species of euglenoids are colorless heterotrophs.

Heterokontophyta (Or Ochrophyta).
