uses transport proteins to move other ions and small molecules across the plasma membrane

facilitated diffusion

the diffusion of water across a selectively permeable membrane

osmosis

when a cell is in a solution that has the same concentration of water and solutes as its cytoplasm

isotonic solution

if a cell is in a solution that has a lower concentration of solute

hypotonic solution

6

the concentration of the solute outside of the cell is higher than inside

hypertonic solution

7

movement of substances across the plasma membrane against a concentration gradient requires energy

active transport

the process by which a cell surrounds a substance inside the cell

endocytosis

9

the secretion of materials at the plasma membrane

exocytosis

10
