Caption: Euglena gracilis cell pellicle and internal cytoplasmic organelles: golgi apparatus (orange and yellow), chloroplast (green), mitochondria (red), pyrenoid body (light yellow), ribosomes (dark blue), vacuole (light purple), nuclear membrane (blue), nucleus (dark purple), chromatin / DNA (purple). Euglena spp. can change their shape readily due to microtubles located beneath their cell membrane / pellicle (dark yellow). 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.
