An organism that causes disease
An organism that feeds on dead matter
An organism that feeds on a living host
An organism that requires oxygen
An organism that does not require oxygen
A state in which members of a population die as quickly as new members are born
Population growth that is unhindered because of the abundance of resources for an ever-increasing population
Population growth that is controlled by limited resources
A temporary union of two organisms for the purpose of DNA transfer
A small, circular section of extra DNA that confers one or more traits to a bacterium and can be reproduced separately from the main bacterial genetic code
The transfer of a DNA segment from a nonfunctional donor cell to that of a functional recipient cell
The process in which infection by a virus results in DNA being transferred from one bacterium to another
The DNA and other essential parts of a bacterium coated with several hard layers
Organisms from the same species that have markedly different traits
The surface underneath the bacterium's cell wall
A semifluid substance inside the plasma membrane
Fibrous bristles that are typically used for grasping surfaces or other bacteria
The surface inside the cell wall; The surface that holds the contents of the bacterium together, regulates the amount of water that the bacterium can absorb, and holds the cell into one of three basic shapes
An outer surface that surrounds the cell wall; Only some bacteria have it
Part of bacteria that allows it to move from one place to another
Non membrane bounded organelles responsible for protein synthesis
What is the most popular means by which bacteria obtain food?
Relying on dead organisms for food
If a bacterium in parasitic, is it heterotrophic or autotrophic?
List the basic steps in asexual reproduction among bacteria.
DNA loop is attached to a point on the membrane, the DNA is copied, the cell elongates, new cell wall material and plasma membrane begin to grow, the bacteria separates into two different bacterium.
A sample of food is dehydrated, which kills all of the bacteria. However, in a few days, bacteria-free water is added to the food in a bacteria-free environment. Nevertheless, microscopic investigations indicate that bacteria are in the food. How did the bacteria get there?
Through asexual reproduction of living bacterium.
What kind of growth does a population of bacteria experience when just a few of them are placed in an environment rich with resources?
A population of bacteria experiences logistic growth. What can you say about its resources of their environment?
The resources are limited in the environment
