LM of Paramecium caudatum,a ciliate protozoan
Numéro d’image : 11905681
| Paramecium protozoan. Light micrograph of Paramecium caudatum,a ciliate protozoan (at centre right). The protozoan has ejected thread- like trichocysts. These are produced by the creature when touched or exposed to certain chemicals. It is believed that they act as a defence mechanism or are used to anchor P. caudatum to stationary objects,although their exact function remains a mystery. P. caudatum propels itself by beating tiny,hair-like structures (cilia) which project from its body. The protozoan lives in stagnant water,feeding on bacteria and plant particles.
