Bacteria Basics
These organisms are unicellular and do not have a nucleus.
What are bacteria?
The process of breaking down dead organisms and waste.
What is decomposition?
Genetic material surrounded by a protein coat that must infect a host cell.
What is a virus?
Protists are eukaryotes, meaning they have this structure.
What is a nucleus?
Fungi cannot make their own food and are classified as these.
What are heterotrophs?
The process bacteria use to reproduce asexually.
What is binary fission?
Bacteria that convert nitrogen gas into a form plants can use.
What are nitrogen-fixing bacteria?
The living cell that a virus must enter to replicate.
What is a host cell?
Animal-like protists are also known as these.
What are protozoans?
The threadlike structures fungi use to absorb nutrients.
What are hyphae?
Small pieces of extra DNA found in some bacteria.
What are plasmids?
The use of bacteria to clean up environmental pollution.
What is bioremediation?
The type of immunity that develops after the body produces antibodies following an infection.
What is acquired immunity?
Three structures protists use for movement.
What are cilia, flagella, and pseudopods?
A network of hyphae is called this.
What is a mycelium?
The process where two bacteria attach and exchange DNA.
What is conjugation?
Medicines used to treat bacterial infections.
What are antibiotics?
Medicines that help prevent viruses from entering cells or stop replication.
What are antiviral medicines?
A protist that moves and feeds using pseudopods.
What is an amoeba?
Fungi called “imperfect” lack this type of reproduction.
What is sexual reproduction?
A structure that allows some bacteria to survive extreme conditions for long periods of time.
What is an endospore?
The process of heating food to kill most harmful bacteria.
What is pasteurization?
A virus that is inactive and has its genetic material built into the host’s DNA is described as this.
What is a latent virus?
A protist covered in cilia that has two types of nuclei.
What is a paramecium?
Two organisms that work together to form a lichen.
What are a fungus and algae (or photosynthetic bacteria)?
