Kingdom Animalia: Defining Characteristics of Invertebrates Quiz and Flashcards

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.
