Euglena gracilis
Euglena gracilis. Light micrograph of a group of Euglena gracilis protists. These organisms possess a unique combination of plant and animal characters. Like the algae,E. gracilis is photosynthetic,possessing the pigments chlorophyll a and b. It uses these to capture energy from the sun,with which it synthesises food in the same way as many plants. It is also,like many protozoa,an active swimmer,moving by beating an extension of its cell membrane known as a flagellum. E. gracilis is therefore considered to be both an alga and a protozoa and is classified accordingly. Differential interference contrast. Magnification unknown
