Unit 9 Reflection

In this unit, we learned about "What on Earth Evolved?" In the beginning of this unit, we were learning about the taxonomic levels in the Classification and Evolutionary  Relationships vodcast, which were Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. We also learned about Binomial Nomenclature, which are Genus and Species names. The first letter of the Genus name is capitalized while the first letter of the Species name is lower-cased, and eventually both words need to be italicized.  Next, we learned about the 3 Domain System which includes Eukarya, Archaea, and Bacteria. Eukarya includes four kingdoms, which are Animalia, Plantae, Fungi, and Protist. Kingdom Protista are unicelluar or multicelluar, Kingdom Plantae is nonvascular and vascular, Kingdom Fungi are heterotrophic decomposers, and Kingdom Animalia are multicelluar heterotrophs. Archae lives near hydrothermal vents, and hot springs, while bacteria contains actinomycetes which produce antibiotics and can be symbiotic and cyano.

  In the Bacteria Viruses Vodcast we learned how bacterial cells contain peptidoglycan, which is a network of sugar polymers cross-lined by polypeptides.  If the peptidoglycan has greater amount on simpler walls, then it is Gram-positive bacteria while if petidoglycan has less amount on simpler walls, then it is gram-negative bacteria.  We also talked about the mobility of bacteria which is  by flagella that they scatter about the surface or concentrated at both ends, and its' importance. In addition, we learned how viruses are small infectious particles that consists nucleic acid enclosing protein coat and the membraneous envelope, and how their genomes consist of RNA or DNA.

Then we go in deeper learning about plants and fungi. Plants are autotrophic, and they contain a Cuticle, Xylem, Pholoem, and a water vascular system. They contain phylas of Bryophyta, Pterlphyta, Gymonosperms, and Angiosperms which subdivdes into Monocots and Dicots. On the other hand, Fungi are multicelluar, heterotrophic, and mutualist organisms that contain hyphae, mycellium, fruiting body, and a spore. They contain Sac Fungi, Club Fungi, and bread molds. Then we start on learning about Invertebrates and their defining characteristics. Sponges are specialized cells that have no body symmetry and can reporduce asexually or sexually.  Cnidarians are the oldest existing group that have specialized cell tissues  and contain classes of Scyohozans, Anthozans, Hydrozans, and Carbozans. Flatworms have simple bilateral animals with an incomplete gut and include classes of planarians, flukes, and tapeworms.  Phylum Molluska share a Radulla, Mantle, and Cteridia, while Anellids contain segmented bodies. Anthropods are classified as trilobites and have joined appendages. They include Crustaceans that contain 2 distinct body sections and a head, thorax, and abdomen. Finally, Echinoderms have a water vascular system and can reproduce asexually and sexually. In Chordates, there are seven classes of vertebrates. Agnatha are one of the first recognizable vertebrates to have segmented bodies. Condricthyes are cartilage fish, and Osteicythes are bony fish. Amphibians contain an aquatic lavae of frogs and are very mobile. Next are Aves, which contained a fused collarbone and feathers, and finally, Mammalia are endotherms that have memory glands, and contain 3 modern groups, which are Montromeres, Marsuipals , and Euteherians.

On my "What on Earth Evolved" I thought the presentation was good overall since I maintained eye contact with the audience the whole time because I memorized what I said. But, I also need talk more about the pictures that I put in the presentation. Like Mr. Orre said, anyone can read the words out of the presentation whenever they want, but it is mainly about describing the pictures I put on the presentation. For my 20 time Ted talk, I need to make my lecture and presentation more of pictures than words.
