lesson 16 osmosis

Question 1

what is osmosis

Answer 1

the diffusion of water from a dilute solution to a concentrated solution through a partially permeable membrane

Question 2

dilute solutions contain what

Answer 2

a high concentration of water

Question 3

concentrated solutions contain what

Answer 3

a lower concentration of water

Question 4

partially permeable membranes allow what

Answer 4

some molecules to pass through but not all molecules

Question 5

the cytoplasm of cells is a relatively concentrated solution, meaning what

Answer 5

it contains a relatively low concentration of water

Question 6

water will move by osmosis how in a cell

Answer 6

from the outside of the cell to the inside of the cell

Question 7

in the case of an animal cell what will happen when osmosis occurs

Answer 7

the water moving in will cause the cell to expand and the cell could even burst

Question 8

if we place an animal cell in a very concentrated solution, then what will occur

Answer 8

the water will move out of the cell by osmosis and the cell will shrink

Question 9

if we place a plant cell in water, what will occur

Answer 9

then water will move into the cell by osmosis and the cell will expand

Question 10

the cell wall prevents the plant cell from what

Answer 10

bursting, instead the cell becomes swollen, scientists call this turgid

Question 11

if we place the plant cell in a concentrated solution, what will occur

Answer 11

what will move out of the cell by osmosis

Question 12

osmosis moving out of the cell in a concentrated solution causes the cell to what

Answer 12

shrink, scientists say that the cell has become flaccid
