Euglena gracilis cell pellicle and internal organelles

Caption: Euglena gracilis cell pellicle and internal cytoplasmic organelles: golgi apparatus(yellow), chloroplast (dark green), mitochondria (red), pyrenoid bodies (light pink), ribosomes (brown), lipid bodies (light green) and vacuole (light blue). Euglena spp. can change their shape readily due to microtubles (blue) located beneath their cell membrane / pellicle (green edge). 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. Magnification*: x3,365 Type: TEM
