Coloured scanning electron micrograph (SEM) of Euglena gracilis, fresh water flagellated protozoan. Euglena spp. are often classified in a group called euglenoids. Euglena sp. normally contain chloroplasts but in prolonged darkness they become heterotrophic and engulf other small organisms. Magnification: x440 when shortest axis printed at 25 millimetres. | |
