Caption: Euglena gracilis cell pellicle and internal cytoplasmic organelles: golgi apparatus (light green and blue), chloroplast (green), mitochondria (dark pink), pyrenoid body (light yellow), ribosomes (brown), vacuole (light blue-green), nuclear membrane (purple), nucleus (dark brown), chromatin / DNA (orange). Euglena spp. can change their shape readily due to microtubles located beneath their cell membrane / pellicle (light orange). Euglena gracilis is a fresh water, flagellated green alga / protozoan often classified in a group called euglenoids. Euglena spp. normally contain chloroplasts but in prolonged darkness they become heterotrophic and engulf other small organisms.
