Paramecium protozoa (Paramecium sp.),coloured scanning electron micrograph (SEM). These protozoa (two seen) are described as ciliate because many cilia (hair-like structures) cover them. Protozoa are single-celled (unicellular) micro-organisms that are eukaryotes,meaning they have a cell nucleus. Paramecia use their cilia to stir up the surrounding liquid and bring food to their feeding areas. They feed mostly on bacteria. The sizes of protozoa range from 5-500 micrometres (millionths of a metre) | |
