Bacterial structure
What are prokaryotes?
These Cells do not have a nucleus
What is lysis?
This happens when a virus causes a host cell to burst open.
What are abiotic factors?
Non-living factors in an ecosystem.
What are biotic factors?
Living factors in an ecosystem such as plants and animals.
What is murein (peptidoglycan)?
This substance makes up the cell wall of eubacteria.
What is the lytic cycle?
This viral cycle ends with the host cell being destroyed.
What are climatic factors?
The average weather conditions that affect a community.
What is competition?
When organisms compete for the same resource like food or space.
What are cocci, bacilli, and spirilla?
These are the three main bacterial shapes.
What is the lysogenic cycle?
This viral cycle occurs when viral DNA joins the host DNA.
What are edaphic factors?
Factors related to soil in an ecosystem.
What is predation?
When one organism hunts and eats another.
What is the Gram stain?
This test stains bacteria purple or pink based on cell wall structure.
What is a provirus (or prophage)?
This term describes viral DNA that becomes part of the host's DNA.
What are aquatic factors?
These include water conditions like salinity and temperature.
What is a food chain?
Only 10% of energy is passed to the next level in this structure.
What is the nucleoid?
This is the region in bacteria where
DNA is found.
What is transduction?
This process allows viral DNA to combine with bacterial DNA and move to another bacterium.
What is an abiotic factor?
The amount of rainfall is an example of this type of factor.
What are producers (autotrophs)?
Organisms that make their own food.
