The protozoan protists are also known as animal-like protists. They are represented by unicellular animals which were earlier placed in the phylum Protozoa under Animal kingdom. They are now identified in four groups zooflagellates, sarcodines, ciliates..

Sexual reproduction is seen in nearly all animals. In animals reproduction also involves production of gametes that are haploid cells . In unicellular organisms like the protozoans, the gamete-producing individuals are called gametocytes. The gametes may be s..

The Animal Kingdom is divided in several phyla mainly on the basis of the cell organisation, symmetry, presence or absence of notochord and body cavity. Animals are arranged progressively from simple single-celled protozoans to highly complex mammal..

Nutrition in Animals - All animals are heterotrophic (there are exceptions like Euglena, which has chlorophyll). The different modes of heterotrophic nutrition have already been dealt with in the earlier part of the chapter. Of all the methods of heterotrophism, holozo..

Animals exhibit a complex body organisation which shows a very clear evolutionary trend. The complexity of animal organisation is seen with reference to features like cellularity, germ layers in the body wall, symmetry of the body parts and the nature of body cav..
