Q

Diffusion travels from a ___ concentration to a ____ concentration

A

high to low

17
Q

what is the concentration gradient

A

Difference in concentration (high-low)

18
Q

Can starch pass through the membrane easily? Why or why not

A

No because it has a large chain; selecively permeable in size

19
Q

Osmosis travels from a ___ to ___ concentration

A

low to high

Hypo to hypertonic

20
Q

Water is polar which means it is hydro___

A

Hydrophilic

21
Q

Factors that make the rate of diffusion increase

A

Increase temperature

Larger concentration gradient

22
Q

what happens when there is greater water pressure inside the cell

A

Turgor pressure

23
Q

what happens when a cells contents shrink but the cell wall keeps its structure

A

Plasmolysis

24
Q

Do channel proteins need ATP? why or why not?

A

No because they move thing like glucose and amino acids across the concentration gradient
