Kingdom      animalia  Introduction: The organisms, which are eukaryotic, multicellular, and heterotrophic, are categorized as Animalia kingdom. Animalia Kingdom: The organisms of Animalia kingdom have no cell-wall. Most of animals of Animalia kingdom are mobile. Classification of Animalia Kingdom Based on the extent and type of the body design differentiation, Animalia kingdom classified as − 1. Porifera 2. Coelenterata 3. Platyhelminthes 4. Nematoda 5. Annelida 6. Arthropoda 7. Mollusca 8. Echinodermata 9. Protochordata 10. Vertebrata 11. Pisces 12. Amphibia 13. Reptilia 14. Aves 15. Mammalia Let’s discuss each of them in brief − Porifera: The literal meaning of ‘porifera’ is the organisms with holes. The organisms of porifera are non-motile and attached to some solid support. The examples of this group are Sycon, Spongilla, Euplectelia, etc. Coelenterata: Organisms of coelenterata group live in water. The organisms of this group have cavity...

Fundamental Unit of Life The fundamental unit of life is cell. Cell was first discovered by Robert Hooke in 1665 in a simple microscope. Animal Cell Structure In 1674, Leeuwenhoek, with the help of developed microscope, discovered the free living cells in pond water. In 1831, Robert Brown had discovered the nucleus in the cell. In 1839, Purkinje used the term ‘protoplasm’ for the fluid substance found in the cell. The cell theory was proposed by Schleiden (1838) and Schwann (1839). According to the cell theory, all the plants and animals are composed of cells and that the cell is the basic unit of life. In 1855, Virchow further expanded the cell theory and suggested that all cells arise from pre-existing cells. In 1940, the discovery of electron microscope made possible to observe and understand the complex structure of the cell. Unicellular Organisms The single cellular organisms, such as Amoeba, Chlamydomonas, Paramoecium, and bacteria, are known as unicellula...
