Organization and Symmetry in Kingdom Animalia

The video tutorial by Professor Dave covers the organization of animals, starting from the development of a blastula and differentiation of cells. It explains the five grades of biological organization: protoplasmic, cellular, cell-tissue, tissue-organ, and organ-system. The tutorial also discusses various types of biological symmetry, including spherical, radial, biradial, and bilateral symmetry, and introduces directional terms and asymmetry in animals. The session concludes with a brief overview of cladistics and sets the stage for exploring different animal phyla in future tutorials.
