Ciliate protozoan membranelles,coloured scanning electron micrograph (SEM). Protozoa are a type of unicellular animal. The ciliate protozoa are so named because of the hair-like cilia which are used for locomotion and sweeping in food. Here,a fused set of cilia (membranelles,upper centre) is used to draw bacteria and other food particles into the oral groove. Ciliate protozoa live in water and are typically invisible to the naked eye,although the largest ciliate can reach a length of 2 millimetres. Magnification: x2500 when printed 10 centimetres wide | |
