Study Notes
- The Kingdom Animalia is a large group of eukaryotic, multicellular organisms that obtain nutrition from external sources. They consist of two main groups: vertebrates (animals with backbones) and invertebrates (animals without backbones).
- Animals are classified using a seven-level scientific system: kingdom, phylum, class, order, family, genus, and species.
- Vertebrates belong to the phylum Chordata and possess a backbone and internal skeletal system. They are classified into seven main classes: Mammalia, Reptilia, Amphibia, Aves, and five other classes of fish.
- Invertebrates make up over 97% of all animals in the Animal Kingdom. They lack a backbone and internal skeletons, some having external skeletons. Invertebrates are classified based on morphology, symmetry, and life cycle.
- Animals exhibit different patterns of cell organization. Three main levels of organization include: cellular level (cells form loose aggregates), tissue level (cells perform the same functions and form tissue), and organizational level (more complex organisms have multiple layers of tissue).
- Invertebrates with tissue level organization have two main layers: ectoderm and endoderm. Ectoderm forms the outer layer of the body, while endoderm forms the inner layer. Some invertebrates also have a middle layer known as mesogloea.
- Vertebrates make up less than 5% of all known animals, while invertebrates make up over 97%. Invertebrates show greater diversity in forms and adaptations.
- The Animal Kingdom is divided into two main groups: vertebrates (animals with a backbone) and invertebrates (animals without a backbone).
- The Animal Kingdom is divided into seven major groups: kingdom, phylum, class, order, family, genus, and species.
