Lab Test 2-Movement Of Molecules/nacl Solution/potatoes

Front 1

diffusion is the net movement of substances from low to high concentration or high to low concentration?

Back 1

high concentration to low concentration

Front 2

is diffusion faster in a gel or a liquid? and why?

Back 2

liquid because liquid molecules are farther apart

Front 3

is diffusion faster in hot or cold water? and why?

Back 3

hot, because the higher the temp the faster molecules move in water

Front 4

what moved through the baggie starch or iodine? and by what process?

Back 4

iodine, diffusion

Front 5

what were the two substances in the NaCl solution?

Back 5

water and sodium chloride

Front 6

what was the solute?

Back 6

sodium chloride

Front 7

what was the solvent?

Back 7

water

Front 8

what was left over in the test tube after the reaction?

Back 8

water

Front 9

how do potato slices feel if the cells are soaked in distilled water?

Back 9

stiff

Front 10

is distilled water hypotonic, isotonic, or hypertonc to the potato cells?

Back 10

hypotonic

Front 11

Have the potato cells lost or gained water?

Back 11

gained

Front 12

Are the potato cells turgid or plasmolyzed

Back 12

turgid

Front 13

is the 10% NaCl hypotonic, isotonic, or hypertonic to the potato cells

Back 13

hypertonic

Front 14

what molecule moves in or out of the potato cells? and by what process?

Back 14

water,osmosis

Front 15

How do potato slices feel if the cells have been soaked in 10% NaCl?

Back 15

limp

Front 16

what solution is hypotonic to blood cells? distilled water, 0.9 NaCl, or 10% NaCl?

Back 16

distilled water

Front 17

what solution is hypertonic to blood cells? distilled water, 0.9 NaCl, or 10% NaCl?

Back 17

10% NaCl

Front 18

what solution is isotonic to blood cells?

Back 18

0.9 NaCl

Front 19

Do blood cells gain or lose in a hypotonic solution?

Back 19

gain

Front 20

Are the cells crenated or hemolyzed?

Back 20

hemolyzed

Front 21

how does a test tube of blood appear when cells are in a hypotonic solution?

Back 21

clear

Front 22

what effect does an isotonic solution have on blood cells?

Back 22

has normal appearence due to no net gain or loss of water

Front 23

do blood cells gain or lose water in a hypertonic solution?

Back 23

lose

Front 24

what molecule moved in or out of cells? and by what process?

Back 24

water crenation

Front 25

are the cells crenated or hemolyzed?

Back 25

crenated

Front 26

how does a test tube of blood appear when cells are in a hypertonic solution?

Back 26

cloudy
