Bacteria…Bacteria EVERYWHERE!!!. Habitat - environment or place where organisms thrive Optimal conditions - ideal temperature, humidity, nutrients Where???? on the tops of mountains the bottom of the deepest oceans in the guts of animals
Bacteria Serrati a bacteria Harvard School of Public Health (Dr. Melvin W. First, Professor Emeritus), United States March 2007 Coliform ( E. coli ) bacteria Ishikawa Health Service Association, Japan September 2000 E. coli, Staphylococcus aurous , candida
Bacteria:. Classification and Structure. What are the 6 Kingdoms?. Archaebacteria Eubacteria Protists Fungi Plants Animals. We are looking at the first two. Archaebacteria Eubacteria. Classification of Bacteria. Archaebacteria: extremists Eubacteria: Heterotrophs
BACTERIA. Biology Chapter 24. Bacteria are very small. This is a pore in human skin and the yellow spheres are bacteria. Bacteria are very small compar-ed to cells with nuclei. Bacteria compared to a white blood cell that is going to eat it. Bacteria.
Bacteria. Previously all classified KINGDOM MONERA. Bacteria Characteristics . Prokaryotic Unicellular Some autotrophic Some heterotrophic Some chemotrophic Contain Cell Walls. Two Kingdoms of Bacteria. Archeabacteria Most primitive organisms on earth Found in very harsh environments
Bacteria. Characteristics. Prokaryotes Microscopic (Eukaryotic cells are at least 10x bigger) Unicellular DNA is a single circular piece of DNA Asexual Reproduction Binary Fission Metabolism Aerobic Anaerobic. Genetic Exchange Conjugation –transfer DNA through contact
Bacteria. Domains. Archaea - ancient prokaryotes Extremophiles Bacteria- cause disease today Peptidoglycan – sugars/ short polypeptides. Cell Shape. Cocci - spherical, rod shaped Clusters or chains Ex: Pneumonia bacteria Spirochetes - spiral shaped
BACTERIA. CLS 212: Medical Microbiology Mrs. Amany Ahmed Niazy. Microorganisms. Cellular. Acellular. Prokaryotes. Eukaryotes. Viruses. Archaea. Fungi . . Bacteria. P rotozoae. Vir. Bacteria are the smallest and most versatile independently living cells known. . Prokaryotes.
Bacteria. Ch 18. Bacteria. Genome – double stranded circular DNA . DNA packed into nucleoid. Reproduction: -Binary Fission - short generation times. http://www.youtube.com/watch?v= gEwzDydciWc. How do bacteria vary genetically?. Mutations Genetic recombination
Bacteria. Bacteria. Prokaryotic Eukaryotic Can be Both. Prokaryotic! Bacteria are the ONLY prokaryotes on Earth!. Remember!. Prokaryotic vs. Eukaryotic Cells. Prokaryotic. Eukaryotic. Larger & more complex Contain a nucleus Contain membrane-bound organelles. Small & simple NO NUCLEUS
