Front 18

movement of small particles across the cell membrane

Back 18

diffusion

Front 19

uses proteins to push particles across

Back 19

facilitated diffusion

Front 20

requires the help of carrier and channel proteins

Back 20

facilitated diffusion

Front 21

these articles move from an area of high concentration to an area of low concentration

Back 21

facilitated diffusion

Front 22

high concentration to low concentration

Back 22

diffusion

Front 23

particles spread out

Back 23

diffusion

Front 24

movement of water through selectively permeable membrane like the cell membrane

Back 24

osmosis

Front 25

water moves across the cell membrane from sn area of high concentration to low concentration

Back 25

osmosis

Front 26

permeable to water, but not to sugar

Back 26

semi-permeable membrane

Front 27

contain high concentration of solute

Back 27

hypertonic

Front 28

contain low concentration of solute

Back 28

hypotonic

Front 29

contain the same concentration of solute as another solution

Back 29

isotonic

Front 30

the water diffuses out of the cell, causing it to shrivel

Back 30

hypertonic

Front 31

diffuses into the cell, causing ti to swell and possible nag explode

Back 31

hypotonic

Front 32

diffuses into and out of the cell at rhe same time

Back 32

isotonic

Front 33

water outside is saltier

Back 33

hypertonic

Front 34

water outside of the cell

Back 34

hypotonic

Front 35

water has an equal amount of salt as the water inside of the cell
