Definitions
The science dealing with the description, identification, naming, and classifying of organisms.
Taxonomy
A saprophyte feeds on this
Dead matter
This infectious agent must infect another cell to reproduce
Virus
The bacteria Strepococcus have what shape and what colony type?
The bacteria are spherical in shape and colonies form chains(strepo = chain, coccus = spherical)
Binomial nomenclature
Naming an organism with its genus and species name
Photoautotrophs such as cyanobacteria derive their energy from this
Sunlight
What is the correct order for the Scientific Classification? (most general to most specific)
Kingdom, Phylum, Class, Order, Family, Genus, Species
This process allows a desirable trait such as antibiotic resistance to be shared with another bacterium
Conjugation
A bacterium's "outboard motor", this structure is composed of the filament, hook, and basal body
Flagellum
Binary fission is an example of this type of reproduction
The scientific name for the polar bear is Ursus maritimus. Which other bear will have the most similarities? Why?
Ailuropoda melanoleuca (Panda Bear) or Ursus arctos (Grizzly Bear)
Ursus arctos (Grizzly Bear) because they are in the same genus
A chemical secreted by a living organism that kills or reduces the spread of other organisms
Antibiotic
Formed when growing conditions become unfavorable, this internal wall protects a bacterium's DNA and ribosome until conditions improve
Endospore
Using bacteria to treat sewage or to remove oil from water in oil spills are examples of this process
First developed in the 1700s by Edward Jenner, this weakened version of a pathogen is used to stimulate the body's immune system to prevent disease
Vaccine
What does a vaccine do to make a person immune to a virus?
A vaccine injects a weakened version of a virus to stimulate the body's immune system to produce antibodies to that virus
In addition to a nucleoid, bacteria often contain these smaller circular DNA molecules that help them survive stressful situations
Plasmids
Yogurts and cheese are manufactured by bacteria through this process
Fermentation
Antibiotics work by attacking this part of a pathogenic bacterium
The cell wall
A bacterium has a new trait because of genetic recombination. If it did NOT participate in conjugation, what made this possible?
The bacterium could have acquired the new trait through transformation or transduction.
