PPT-2.2: PROKARYOTIC CELLS

221 222 Ultrastructure of Ecoli Mesosome Plasmid 223 Electron micrograph of Ecoli Nucleoid region cytoplasm IB Question Draw and label a generalized prokaryotic cell as seen under the electron microscope . Lily Chan and Tim Johnstone. Transfection:. . to transfer DNA into cells (either eukaryotic or prokaryotic) not through use of a viral vector. The approaches for eukaryotic and prokaryotic-cell . transfection are slightly . AJ Scielzo. Prokaryotic Flagella . Long, threadlike structures protruding from the outside surface of the cell . Main function is movement. Prokaryotic flagella are protein fibers that extend from the cell. A. Generalized Structure. 1. Cell Appendages. A) Flagella. 1) Functions in movement of the cell. 2) 3 components. Prokaryotic Cell Structure. a) Filament . i) Whip-like, helical structure. b) Hook . i) Holds the filament. Eukaryotes, Prokaryotes and Measuring Cells. Lesson Objectives. To understand the difference between eukaryotic and prokaryotic cells.. To describe the features of a prokaryotic cell such as a bacterium.. A. Introduction – There are multiple criteria by which you can classify an organism. 1. Metabolic Activities (Carbon, Energy & Oxygen sources). A) Recall that microbes may vary in their carbon & energy sources. 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. Endosymbiosis. h. eterotrophic eukaryote. Examine these diagrams showing . how an ancestor to eukaryotic cells may have engulfed smaller heterotrophic prokaryotic cells that began producing ATP for it. Group # 1. Akhtar. Ali. Lucile McCook.

Tissue. Organ. Organ System. Organism. Division of Cells. Eukaryotic Cells. Literally means “True nucleus”. Have a nucleus. Complex Cells. Have membrane-bound organelles. Two Basic Types. Remember….cells are the basic unit of life for ALL living things.. There are two basic types of cells:. Prokaryotic cells . – found in bacteria. Eukaryotic cells . – found in . CHAPTER 27. PROKARYOTIC ADAPTATIONS. typical prokaryote:. 0.5 -5 microns. unicellular. variety of shapes. cocci. (spherical). bacilli (rods). spirochetes (corkscrews). Cell-Surface Structures. nearly all have cell wall. Lack a nucleus. DNA is naked, a single loop not bound in a chromosome. May contain plasmids (small circular fragments of DNA). Have ribosomes, but no other organelles.. DNA present as a long circular molecule.. 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 . P & E UKARYOTIC C ELLS  As you have already learned, everything is made up of living cells.  And the cells themselves are made up of many different parts .  There are many different cell
