CHAPTER 4 ANIMAL KINGDOM Animal Kingdom is characterized by multicellular‚ eukaryotic organisms. The cells lack cell walls. They ingest and digest food (holozoic)‚ hence they are heterotrophic. Higher forms show elaborate sensory and neuromotor systems. Majority of them are motile. Reproduction is mostly sexual and embryological development is present in them. About 1.2 million species of animals are described till now. The classification helps to assign a systematic position to newly described

Animal Kingdom The animal kingdom is a taxonomic kingdom composed of multicellular‚ eukaryotic organisms. Mostly‚ their body structures become fixed as they develop‚ yet still some organisms in this kingdom have the ability to undergo metamorphosis. The majority of these organisms are motile‚ which means they can move on their own and with spontaneity. All animals are heterotrophic‚ which implies that they depend on other organisms for food. Animals live in places that provide their necessities

You may have learned in an earlier course that sponges are in the phylum Porifera. This group is now known to be polyphyletic‚ and all sponges belong to either phylum Calcarea or phylum Silicea. They are the simplest animals and lack true tissues. Label the following: pores‚ spongocoel‚ epidermis‚ amoebocytes‚ choanocyte‚ flagellum‚ spicules‚ epidermis‚ and mesohyl. On this

Sponges range in height from about 1cm to 2cm. 4. More than 5000 species of sponges are found. 5. All are marine‚ while some are fresh water. 6. The central body cavity is called spongocoel. 7. A single large opening is called as osculum. 8. They are filter feeders. 9. Body lining is formed by flagellated cells

If not‚ which phyla have fewer than three germ layers? No‚ not all organisms on the table have three germ layers such as the sponges. The phyla’s that do have three germ layers are the: Flatworm‚ roundworm‚ mollusks‚ echinoidea‚ chordates and the arthropods. (Clc.U.C.edu. 1997) 4. One phylum on the table has more species

the Arthropod phylum. In fact‚ some scientists believe that if we were to identify all species in the tropical rain forests the ranks of Arthropod would swell to over 10 million species! Most people do not normally think of a clam‚ a jellyfish‚ or an earthworm as an animal. Yet all of them belong to the kingdom of animals. The science of classifying organisms is called taxonomy. In order to study living things‚ scientists classify each organism according to its: Kingdom Phylum Class Order Family
