PPT-Origins of Eukaryotic Diversity – Protists Diversity

For Lecture Make sure you know the names and characteristics of the taxa at the levels indicated by the red arrows Water Molds Oomycota Characteristics Nucleus Eukaryotic Membranebound organelles. Kingdom Protista. A. Sometimes not considered a true kingdom because the organisms vary tremendously from one to another. The only universal characteristic among the group is that they are all eukaryotic.. TSW – Recognize that the presence of a nucleus determines whether a cell is prokaryotic or eukaryotic. 6.12B. Cells. There are two . basic types . of cells. Prokaryotes. or prokaryotic cells . Eukaryotes. 2.3.1, 2.3.2: Liver cell. 2.3.3: Electron micrograph of liver cell (rat). Glycogen. 2.3.4: Prokaryotic VS Eukaryotic cell. FEATURE. Prokaryotic cell. Eukaryotic cell. DNA. Naked DNA. DNA associated. with proteins. Unicellular Organisms. Some organisms are made up of only . one cell. .. We call these organisms . unicellular. which means one-celled.. These organisms are much . simpler. than most organisms that are made up of many cells.. Protists are a range of organisms that have many different features. This makes them really hard to classify.. Protists. While protists range significantly they do share common characteristics:. Most are unicellular. Which is the evolutionary difference between the salamander and the lizard? . a. claws or nails c. jaws. b. . fur; mammary glands d. . lungs. The 3 Domains of Life Notes . (page 59). DOMAINS.

Animal Cell. Plant Cell. Compare Animal and Plant cell. What Are Protists?. A group of one-celled organisms with well defined nuclei. All protists live in moist surroundings. Many protists possess both plant-like and animal-like features. Animal like protists are called PROTOZOAN . Eukaryotic Cell. 3. Eu. = True. Karyon. = Nucleus. B- The Eukaryotic Cell. Animal Cell.

Protists. are….. organisms that cannot be classified into any other group (plant, animal, fungus, bacteria). o. rganisms that are typically made up of just one cell. o. rganisms that can be made up of many cells. The Fungi. The . Fungi. A. Once thought to be plants but the cell wall is made of chitin rather than cellulose and these are not photosynthetic. B. Instead they are saprobic organisms that frequently live off of dead organic matter. Eukaryotic translation. Eukaryotic mRNAs are characterized by two post-transcriptional modifications: the 5-terminal 7methyl-GTP cap and the 3-terminal poly(A) tail .. The 7methyl-GTP cap is essential for mRNA binding by eukaryotic . Federoff. Bacterial Diseases. Microorganisms—viruses and prokaryotes—that cause disease are called . pathogens. . Louis Pasteur helped to establish what has become known as the . germ theory of disease .
