EXAM 1: Ch.1 The Main Themes of Microbiology
Microorganisms include:
1. Bacteria 2. Viruses 3. Fungi 4. Protozoa 5. Helminths (worms) 6. Algae
Define photosynthesis and decomposition
1. Photosynthesis: Light fueled conversion of carbon dioxide to organic material 2. Decomposition: Breakdown of dead matter and wastes into simple compounds
For prokaryote, eukaryote and viruses: 1. unicellular, acellular, or multicellular? 2. Membrane-bound or contains no membrane bound organelles ? 3. Contain nuclei? *virus is specific to what it contains
1. Prokaryote - microscopic, unicellular organisms, lack nuclei and membrane-bound organelles 2. Eukaryote - unicellular (microscopic) and multicellular, nucleus and membrane-bound organelles 3. Viruses - Acellular, parasitic particles composed of a nucleic acid and protein
Taxonomy
Classification, naming and identification and of microorganisms
Which of the following does NOT describe a fungus? A. Contains a nucleus B. Has 80S Ribosomes C. Useful in Decomposition D. Is photosynthetic
D. Is photosynthetic
Prokaryote VS Eukaryote cell structure: 1. Which is simple and complex 2. Nucleus structure
Prokaryotes (pre-nucleus): Simple cells - Eukaryotes (true nucleus): Complex cells
Mycology
The study of *fungi*; a group of eukaryotes that includes both microscopic eukaryotes (mold & yeast) and larger organisms ( mushrooms and puffballs)
Bacteriology
The study of bacteria; small single celled prokaryotic organisms
Morphology
The study of detailed structure of microorganisms
Microbial Ecology
The study of interrelationships between microbes and the environment; the roles of the microorganisms in the nutrient cycle and natural ecosystem
Physiology in microbiology
The study of microbial function (metabolism) at the cellular and molecular level
Parasitology
The study of parasitism & parasitic organisms; traditionally including pathogenic protozoa, helminth worms, & certain insects
Phycology and Algology
The study of simple photosynthetic eukaryotes; algae that range from single-celled forms to large seaweed
Microbial genetics , Microbial biology
The study of the function of genetic material and biochemical reactions that make up a cells metabolism
Protozoology
The study of the protozoa; animal like and mostly single celled eukaryotes
Virology
The study of viruses; non cellular particles that parasitize (infest) cells
T/F: Bacteria-like organisms have existed on earth for about 3.5 billion years
True
T/F:Parasites live on or in the body of another organism called the host and it damages the host.
True
