Vorticella protozoa. Darkfield illuminated polarised light micrograph of a colony of Vorticella sp. ciliate protozoa, showing the symbiotic green algae in their bodies . These ciliate protozoa consist of a bell-shaped head and a stalk that is anchored to the substrate. Cilia attached to the head are used to capture food and also for movement. Photosynthetic green algae held within their bodies also produces nutrients used by the protozoan. Magnification: x28, when printed 10 centimetres wide. | |
