Chapter 10
Bacteria are prokaryotes which means they
have a bilayered phospholipid cell membrane
Viruses are
nonliving
Why do some viruses seem to go away and then return later, like a cold sore??
the virus had entered the lysogenic cycle
What is one characteristics that the kingdom Protista shares with bacteria
Unicellular
One of the 1st groups of living things
Protista that resembles plants can be subdivided into six groups:
Diatoms
Euglenoids
Dinoflagellates
Red algae
Brown algae
green algae
The outer covering of a bacteria cell is called
a cell wall
A virus consists of
RNA or DNA and a cell membrane
How do bacteria reproduce the majority of the time
Binary fission
What is one characteristics that the kingdom Protista has that is difference from bacteria
Has a nucleus
Live in watery environments
what plant-like protista group have a glass-like cell wall
Diatoms
bacteria that helps break down dead organisms in the environment are called
decomposers
How do viruses reproduce
Inserting DNA into the host cell
What type of medicine kills bacteria??
Antibiotics
The word protozoans mean
1st animal
Algae can only be unicellular or multicellular
multicellular
a disease causing organism is called
pathogen
Vaccines can be used to prevent viral infection by
creating an immune response in the host
What is produced by an infected host cell and released when the cell bursts
interferon
what is a job of a contractile vacuoles
controls amount of water inside
Amoebas reproduce by going through
binary fission
All bacteria are
Unicellular
Antiviral drugs that are used after infection often prevent
reinfection by other viruses
Bacteria can move. The cell part that helps them to be mobile is called the
flagella
what is that job of a food vacuole
where food is digested
what algae can be used for hair conditioner
Red algae
