100
What are the three basic bacterial cell shapes?
What is spherical, rodlike, spiral
100
What are two ways that autotrophic bacteria use energy to make food?
What is from the sun's energy and from chemical substances in their environment.
100
What type of reproduction results in bacteria that is genetically different? What is this process called?
What is sexual reproduction. Conjugation.
100
What is pasteurization?
What is the process in which food is heated to a temperature that is high enough to kill harmful bacteria without changing the taste of the food.
100
How does a bacterium move?
What is if a bacterium has a flagellum or flagella, this structure helps it move. If the bacterium has no flagella, it cannot move on its own and will be carried from place to place by the air, water currents, objects, etc.
200
What is the function of the cell membrane?
What is it controls what materials pass in and out of the cell.
200
What is respiration?
What is the process of breaking down food to release its energy.
200
What type of reproduction is binary fission? Describe the process.
What is asexual reproduction. When one cell divides to form two IDENTICAL cells.
200
How do bacteria help in oxygen production?
What is as autotrophic bacteria use the sun's energy to produce food, they release oxygen as a waste product into the air.
200
If a bacterium has almost completed binary fission, how would you expect the cell to look?
What is the cell would have duplicated it's genetic material and separated it into two separate cells. Before the process is complete, the cell will have almost completed separated itself from the other to form two completely identical cells.
300
What unit of measurement is bacteria measured in? What is larger, a bacterium or a virus?
What is micrometers. A bacterium.
300
What do heterotrophic bacteria consume to release energy?
What is heterotrophic bacteria must consume other organisms or food that other organisms make. (Examples: milk, meat, decaying leaves).
300
What does bacteria need in order to reproduce frequently?
What is plenty of food, the right temperature, and other suitable conditions.
300
Give an example of how bacteria would help clean the Earth's water.
What is there are some bacteria that consume substances like oil and gasoline. These bacteria are used to help clean up oil spills or gasoline leaks.
300
What is the function of a genetic material of a bacterium?
What is it contains the instructions for all the cell's functions.
400
What is the function of a flagellum?
What is to help the cell move.
400
What do most bacteria need to break down their food?
What is oxygen.
400
In what conditions would an endospore form (be specific)? What is the function of an endospore?
What is in harsh conditions: extreme temperatures, lack of food. Endospores protect the bacteria cells from these harsh conditions.
400
What has bacteria helped scientists accomplish regarding medicine? Give an example that we have discussed in class.
What is scientists have manipulated the genetic material in some bacteria so that produce medicine. Example: some bacteria can produce human insulin which helps diabetics.
400
What is found in the cytoplasm of bacterial cells?
What is the genetic material.
500
This is the gel-like material inside the cell membrane.
What is the cytoplasm.
500
True or False: All bacteria are autotrophs. (If false, please provide the correct answer).
What is false. Bacteria can be autotrophs or heterotrophs.
500
During this process, one bacterium transfers some of its genetic material into another bacterium.
What is conjugation.
500
What role do bacterial decomposers play in the environment?
What is bacteria breaks down large chemicals in dead organisms into basic chemicals that other organisms can reuse.
500
What determines the shape of a bacterial cell?
What is the chemical makeup of the cell wall.
