What is a sphere-shaped bacterial cell?
coccus
What is coccus?
Any sphere-shaped bacterial cell.
What is a rod-shaped bacterial cell?
Bacillus
What is bacillus?
Any rod-shaped bacterial cell?
What is a spirillum cell?
Any genus of long-curved bacteria with a bunch of flagella at both ends.
What do these three bacterial cells have in common?
They have cytoplasm, free-floating DNA, ribosome, cell wall, cell membrane, prokaryote
What does bacillus have that others don’t?
Bacillus has a tail that is called a flagellum
What are two kinds of passive transport?
Simple diffusion and facilitated diffusion
Where does the passive transport occur?
plasma membrane
What enzyme does facilitate diffusion have?
Carrier protein
What is different about both diffusions?
Simple diffusion just has the cells go through the membrane, but facilitated diffusion goes through a carrier protein.
Is passive transport hypertonic or hypotonic?
hypertonic
Is passive transport high to low, or low to high concentration?
High to low
What’s special about facilitated diffusion compared to simple diffusion?
Because the facilitated diffusion has carrier proteins, they decide which goes in and out.
What is active transport also called?
Protein pump
Is active transport hypertonic or hypotonic?
hypotonic
Is passive transport high to low, or low to high concentration?
Low to High
What does it mean when something is hypertonic?
It means that it has more solute than the other.
What does it mean when something is hypotonic?
It means that it has less solute than the other.
Does hypertonic have less water or more water?
less water
Does hypotonic have less water or more water?
more water
What relationship does water and solute have?
Inverse relationship
What happens to the water during hypertonic?
water goes into hypertonic
What happens to the water during hypotonic?
water goes out of the hypotonic
