High solute: low water

Plasmolysis

18
Q

Isotonic and word for it

A

Equal solute: equal water

19
Q

Bacteria and plants prevents and name

A

Cell wall prevents over expanding

Tugor pressure

20
Q

Protists

A

Contractile vacuole collects and pumps out water to prevent over expanding

21
Q

Salt water fish

A

Pumps out salt water through specialized gills so they don’t dehydrate

22
Q

Animal cells

A

Kidneys keep the blood isotonic by removal of excess salt

23
Q

What is passive transport affected by

A

Temperature, pressure, and concentration gradient
