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

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.

CHAPTER NO-5 KINGDOM ANIMALIA Phylum Porifera (GK: Porous = Pores + Ferro = form) Main characters: 1. They are commonly called as sponges. 2. They are sessile animals. 3. 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

this experiment‚ we are required to observe‚ explain‚ identify and recognize the phylum under Kingdom Animalia. The phylum that we need to identify was Phylum Porifera‚ Phylum Cnidaria‚ Phylum platyhelminthes‚ Phylum Nematoda‚ Phylum Rotifera‚ Phylum Mollusca‚ Phylum Arthropoda‚ Phylum Echinodermata‚ Subphylum Cephalochordata and Subphylum Vertebrata (Fishes). Phylum Porifera The characteristic of members of Phylum porifera include asymmetrical or radial symmetry body plan. There are three types

find a chart that may help you to organize this knowledge. Concept 33.1 Sponges are basal animals that lack true tissues 1. 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
