KINGDOM ANIMALIA

• Kingdom Animalia is a large group that consists of eukaryotic, multicellular organisms that are heterotrophic in nature
• Animalia are unable to produce their own food
• Animal cells lack a cell wall that is present in plant cell
• The majority of animals are motile which allow them to effectively respond to stimuli and find food
• Vertebrates are animals with a backbone, for example human, fishes, amphibians, reptiles, birds, and mammals
• Invertebrates are animals that lack a backbone for example sea-tars, sea-urchins, earthworms, sponges, jellyfish, lobsters, crabs, insects, spiders, snails, clams, and squid
• Vertebrates including all animals are classified under the subphylum vertebrata
• Sponges the cells are arranged as loose cell aggregates the exhibit ( cellular level of organization)
• Cells performing the same function are arranged into tissues, hence is called (tissue level of organization)
