PPT-Prokaryotic Cell Structure

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!. 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. 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. 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. 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. 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. . PROKARYOTES. EUKARYOTES. CYTOPLASM. Cell Membrane. DNA. Always single-celled. No Nucleus. DNA is a simple,. Single loop. Small Cells. (1 – 10 . um. ). Bacteria. . Can be single- or multicellular . 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. Recall your work yesterday. When classifying cells, what are the two groups scientists separate cells into? . USING A MICROSCOPE. Light Microscopes and Total Power Magnification. Uses. We can use microscopes to observe cells in greater detail. 1 Professor Marc C Lavoiemarc.lavoie@cavehill.uwi.edu MICRO-ORGANISMS PROKARYOTES EUKARYOTES BACTERIA ARCHAEA AMOEBOZOA ARCHAEPLASTIDA CHROMALVEOLATA EXCAVATA VIRUSES RHIZARIA OPISTOKONTA What are Arc . How are Prokaryotes Different from Eukaryotes?. The way their DNA is packaged. No nucleus. Not wrapped around . histones. The makeup of their cell wall. Bacteria- peptidoglycan. Archae- tough and made of other chemicals, distinct to them. 4. Bacteria that divide in multiple planes and form grapelike clusters are called. streptococci.. staphylococci.. coccobacilli.. vibrios..
