Euglenoids - Phylum Euglenophyta
Euglenoids are the least algae-like of the algae. They are unicellular, motile, and lack a cell wall. For this reason, they are often classified as protozoans. However, most euglenoids are photosynthetic, containing chlorophylls a and c, and carotenoids. Their motility is typically generated by one anterior flagellum, which beats back and forth in a whip-like motion. Euglenoids reproduce by longitudinal mitotic cell division. A freshwater genus common in arctic mosses, Euglena has a phototropic stigma, which allows it to move towards a light source and increase its photosynthetic efficiency. Euglenoids are found in both fresh and marine water habitats in Canada's Arctic.
