Part Two: 1. Which phyla lack organs? What type of Symmetry do they have?
The phyla that lack organs are: Sponges, Jellyfish, Roundworm and the flatworm. The sponges have symmetry and the jellyfish is radial. The roundworm and the flatworm are both bilateral symmetry. 2. List all of the Phyla that show cephalization.
The Phyla that show cephalization are: Platyhelminthes, Nematode, Annelida, Mollusca, Arthropoda, and the Chordata. (esu.edu) 3. Do all organisms on the table have three germ layers (endoderm, ectoderm, and mesoderm)? 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 that all the others. State the name of this phylum, and provide several different examples of the species found in the phylum.
The phylum that has more species than the others is the Arthropoda. Examples found in the arthropoda are: cockroachs, ants, flies, bees, beetles, and butterflies. (Biology Questions (2003) 5. Fish do not all have the same skeletal structure. Describe the differences among fish from the most primitive to the more advanced type of fish. The primitive fish have more skeletons and the advanced fish have more muscles. (creation wiki, 2007) 6. Describe the three types of mammals based on how their young develop. The three types of mammals based on the how their young develop are: Monotremes, Marsupials, and Placental. The Marsupials developed in a pouch and the Monotremes are egg laying mammals and the Placental are mammals that develop in the womb. (Life 123, 2010)

    Organism two is yeast, which is apart of the fungi kingdom, evident due to its small circular transparent cells. Organisms in the fungi kingdom are mostly multicellular eukaryotes that reproduce both sexually and asexually. Fungi are also heterotrophs, meaning they gain energy from the consumption of other organisms. Organism three is a Daphnia which is a common water flea with a transparent body. Daphnias are apart of the Animalia kingdom, making it eukarya. Organisms in the kingdom Animalia are also multicellular eukaryotes that are heterotrophs and reproduce sexually. Organism four is a paramecium which is a single-celled eukaryote with an evident nucleus in the center of the cell. Parameciums are apart of the Protista kingdom and are mostly unicellular eukaryotes. Organisms such as parameciums in the Protista kingdom also reproduce both sexually and asexually while also being both heterotrophs and autotrophs. Lastly, organism five, also known as Euglena, is a unicellular eukaryote that is also apart of the Protista kingdom. Euglenas also reproduce asexually and are…
