Major evolutionary changes In this lab we looked at the Animalia and Fungi kingdoms and the Porifera and Cnidaria phylums While looking at these we compared the differences and similarities between them There were evolutionary changes present that we were able to classify while looking at each of the specimens The first characteristics included was the presence of cell walls specialized cells and external digestion The spore s presence was one of the first characteristics I included in the cladogram which was included in the specimens coprinus rhizopus penicillium All these have asexual reproduction because of the presence of spores The next characteristic given was unique cells totipotent cells sessile adults and motile cells This included the specimens sponges mushrooms The second trait I included on the cladogram was the ability to absorb water and take it in These specimens obtain a special ability that allows them to do this unlike the specimens coprinus rhizopus and penicillium We are able to determine this because of the given characteristic of them having choanocytes which allows water to absorb through the specimens For the specimens Coral Hydra and Obelia there were given characteristics on the cladogram such as the presence of cnidocytes alternate sexual medusa nerve nets and a gastrovascular cavity My last two traits that I then included that separated these specimens from the others was radial symmetry and the presence of tissues Their radial symmetry is proven from their unique structures like the gastrovascular cavity and since all the specimens have nerve nets that means that they have tissue present All these characteristics show the adaptation to all the organisms that classify them differently They have similarities and differences that helps you determine them from one another By looking at the given characteristics to the specimens you are able to determine their classified traits
