1. BELL WORK: Answer the question below: Which two organisms are most closely related? a. Lamprey and Tunab. Salamander and Turtle c.Turtle and Leopard d. Lancelet and Leopard

2. Set up the next TWO pages in your journal…(NO Cornell notes!) Page: 54 Date: 1-27-15 Title: Kingdoms Chart Page: 55 Date: 1-27-15 Title: Bacteria Essential Question: How do I compare and contrast archaebacteria and eubacteria?

3. Broadest, most inclusive taxon The three domains are: 1.Archaea (unicellular prokaryotes) 2.Bacteria (unicellular prokaryotes) 3.Eukarya (eukaryotes) Domain

4. 3 Domains Archaea Bacteria Eukaryota 6 Kingdoms Archaebacteria Eubacteria Plantae Fungi Animalia Protista

5. Unicellular: made of one cell Multicellular: made of two or more cells Autotroph: able to produce its own food Heterotroph: obtains nutrients from its environment or other organisms

6. Domain Archaea

7. Organisms in the Archaebacteria kingdom are unicellular prokaryotes. They have no membrane bound nucleus or organelles in their single celled bodies. Archaebacteria are similar in size and shape to eubacteria. The cell walls of archaebacteria are different from both eubacteria and eukaryotes because they do not contain the chemical peptidoglycan. Like eubacteria, archaebacteria reproduce asexually or sexually through cell division. They can also be autotrophic, making their own food, or heterotrophic, obtaining food from their environment, just like eubacteria. Some archaebacteria are extremophiles, living in extreme environments such as in hot springs, extremely acidic environments, polar seas, and even in extremely salty water.

11. Organisms in the Eubacteria kingdom are unicellular prokaryotes. Prokaryotes do not have a membrane bound nucleus or membrane bound organelles. Eubacteria are found in almost all habitats. The cell walls of Eubacteria contain the chemical peptidoglycan. Some eubacteria remain independent as single cells and other group into colonies. Eubacteria reproduce asexually or sexually through cell division. Some eubacteria are autotrophic, making their own food, and others are heterotrophic, taking in nutrients from their environment. Eubacteria can cause various diseases, from strep throat to Rocky Mountain spotted fever, but they can also be very helpful. Lactobacillus is used to help make foods like cheese and yogurt, and is also present in the human digestive system. Decomposing organic matter and cycling nitrogen are also important functions of eubacteria.
