Back 1

semipermeable

Front 2

the movement of molecules from an area of high concentration to an area of low concentration is ____

Back 2

diffusion

Front 3

a(n) ____ is the difference between the concentration of a particular molecule in one area and the concentration in an adjacent area

Back 3

concentration gradient

Front 4

the diffusion of water across a semipermeable membrane is called ____

Back 4

osmosis

Front 5

in a(n) ____, the concentration of solutes outside the cell is higher than the concentration of solutes inside the cell

Back 5

hypertonic solution

Front 6

the concentration of solutes in a(n) ____ is lower outside the cell than the concentration of solutes inside the cell

Back 6

hypotonic solution

Front 7

the concentratin of solutes in a(n) ____ equals the concentration of solutes inside the cell

Back 7

isotonic

Front 8

the use of carrier proteins for diffusion is called ____

Back 8

facciliated diffusion

Front 9

the process of ____ is defined as the use of energy to carry molecules across the membrane

Back 9

active transport

Front 10

in the process of ____, large molecules, food, and other substances are packaged and moved across the membrane

Back 10

bulk transport

Front 11

how do facilitated diffusion and active transport differ?

Back 11

faciliated diffusion doesn't need energy while active transport requires energy

Front 12

how do endocytosis and exocytosis differ?

Back 12

endocytosis takes things into the cell while exocytosis moves things out of the cell

Front 13

What is the difference between pinocytosis and phagocytosis?

Back 13

pinocytosis lets liquid into the cell while phagocytosis lets particles into the cell

Front 14

what would happen to a cell in a hypertonic solution?

Back 14

it would shrink

Front 15

what would happene to a cell in a hypotonic solution?

Back 15

it would burst
