A Generalized Structure 1 Cell Appendages A Flagella 1 Functions in movement of the cell 2 3 components Prokaryotic Cell Structure a Filament i Whiplike helical structure b Hook i Holds the filament. This organelle contains DNA and controls the cell. Nucleus. Which scientist said “All animals are made of cells”?. Schwann. This . organelle p. roduces ATP (energy) for the cell. Mitochondria . List the three parts of the cell theory!. OCR AS Biology. Unit 1: Cells, Exchange and Transport. Learning objectives. To understand and discuss the basis of cell theory based upon milestones in cell biology. To carry out practical work on cell size and magnifications using a light microscope. Prokaryotic vs. Eukaryotic Cells. 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. 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. Note that the ATG codon encodes both start and methionine . Prokaryotic genes have a simple one-dimensional structure. 5’→. ←. 5’. 5’→. ←. 5’. Start codon. Stop codon. ATG. TAG. ATG. AAA. Cell theory. Cell organization and homeostasis. Studying cells – microscopy and fractionation. Eukaryotic vs. prokaryotic cells. Compartments in eukaryotic cells (cell regions, organelles). Cytoskeleton. 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.. 2.2.1, 2.2.2: Ultrastructure of . E.coli. Mesosome. Plasmid. 2.2.3: Electron micrograph of . E.coli. Nucleoid region. cytoplasm. IB Question: . Draw and label a generalized prokaryotic cell as seen under the electron microscope. . 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. 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. Remember our procedures! Come in and quietly get your focus lesson and pencil box. Begin working immediately!. Complete the Taking it to the Next Level Column! . Amylase vs Amylose. *Have you completed every . Unit. Context of Unit in Course .
