Biology Animal Phylums "Write a three sentence description for each phylum and list two examples for each. Also‚ draw a picture of a common example from each. (or cut out of a magazine). You will be graded on how accurate your information is as well as neatness." Sponges (Porifera): Poriferans don’t have mouths; instead‚ they have tiny pores in their outer walls through which water is drawn. Cells in the sponge walls filter nutrients from the water as the water is carried through the body

Cladograms are a way for us to observe and analyze characteristics and evolutionary change between two phylums. Starting out with a character matrix allows us to determine synapomorphies and apomorphies between theses two group‚ allowing us to construct the cladogram (Reece). My cladogram consisted of various phylums from the Animal Kingdom. The outgroup for my cladogram was the Choanoflagellates due to the fact that “they are the closest‚ living‚ unicellular relatives of animals” (Leadbeater).

Animal Phylum Poster/Display Project Each student will select a major group of animals to research and ultimately create a poster or display to help explain the group of animals belonging to each class. Be sure to first read your textbook on the group as well as consult general resources before getting into specific resource materials. Students will be graded primarily on the content of the information as well as the creativity of the poster or display. The entire project is worth 75 points

suspended organs to help them prevent injury‚ enables internal organs to grow and move independently from the outer body wall. Acoelomates‚ though‚ lack a cavity between the digestive tract and the outer body wall. An example of an acoelomate would be a flatworm‚ or planarian‚ While an example of a coelomate would be a rotifer. The differences between protostome and deuterostome development are the characteristics in their cleavage‚ their coelom formation‚ and the fate of their blastopore

that can be seen as a white spot where the planarian was bisected (4). The planarian then regenerate a head from the cut of tail portion or a tail from the cut portion (4). It then takes about two weeks for the planarian to fully regenerate (4). A flatworm once survived being cut into 279 pieces and grew new bodies for every single one (el-Showk 1). Planaria do not have anatomical marks on their bodies‚ therefore it is harder to track their regeneration (Levin
