The Protozoan Cell

Part of the A Functional Biology of Free-Living Protozoa book series (FBS)


The unicellular organisms which constitute the Protozoa exhibit considerable morphological and physiological diversity. Although the majority resemble members of the Animal Kingdom in their feeding behaviour, some members of the Protozoa possess the fundamental plant characteristic of autotrophic nutrition. In a considerable number of species possessing chloroplasts and an autotrophic capacity, some degree of heterotrophy must also be practised, so that some protozoans sit on the boundary between a plant-like nutrition and an animal-like nutrition.
