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
