Paramecium Protozoan,light Micrograph
Photograph - Photograph
Paramecium bursaria protozoan, differential interference contrast micrograph. This ciliate protozoan inhabits freshwater, where it feeds mainly on bacteria. It moves by beating its cilia, hair-like extensions that cover its body. The small green bodies inside the protozoan are individual Zoochlorella sp. algae, which have a symbiotic relationship with the protozoan. They photosynthesise inside the Paramecium, providing it with sugars and oxygen, while deriving protection from their host. Magnification x340 when printed 10cm wide.
