Kingdom Animalia Experiment
Disscusion
In 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 of cells which is pinacocytes, mesenchyme cells (amoebocytes) and choanocytes. The central cavity or several branching chambers, thru which water flows for filter feeding and the members under Phylum Porifera do not have tissues or organs. The example of animals that are classify under Phylum Porifera is sponge. Sponge cells are specialized for particular functions (division of labor). Pinacocytes are the “skin cells” of sponges. They are thin, leathery and tightly packed together, may be slightly contractile and help sponge change shape. Some pinacocytes specialized into porocytes, which regulate water circulation.
Phylum Cnidaria
Cnidarians include corals, jellies, and hydras. These animals have a diplobastic, radially symmetrical body plan that includes a gastrovascular cavity with a single opening that serves as both mouth and anus. The basic body plan of a cnidarians is a sac with a central digestive compartment, the gastrovascular cavity. There are two variations on this body plan : the sessile body polyp and the motile medusa. Polyps are cylindrical forms that adhere to the substrate by the eboral end of their body (the end opposite the mouth) and extend their tentacles, waiting for prey. A medusa is a flattened, mouth down version of the polyp. It moves freely in flattened, mouth-down version of the polyp. It moves freely in the water by a combination of passive drifting and contractions of its b ell-shaped body. Cnidarians are carnivores that
