Paramecium sp. Watercolour artwork of Paramecium sp.,a ciliate protozoan. This single-celled organism is covered in hair-like cilia,aiding locomotion and the movement of food particles towards its oral groove (dark brown,at centre). Directly below the oral groove are the macronucleus (red) and micronucleus (purple),containing the genetic material. The two contractile vacuoles (white) help to maintain the water balance within the Paramecium. The other circular objects within the cytoplasm (yellow) are food vacuoles in which engulfed particles,such as bacteria,are digested. Paramecium sp. are plentiful in freshwater ponds | |
