B1.7 OSMOSIS

Question 1

what’s the name of 2 solutions within the same concentrations

Answer 1

isotonic

Question 2

what’s the name if the solution is more concentrated ( more solute, less water)

Answer 2

hypertonic

Question 3

what’s the name if the solution is more dilute ( more water, less solution )

Answer 3

hypotonic

Question 4

what’s osmosis

Answer 4

diffusion of water across a partially permeable membrane from a dilute to a more concentrated solution

Question 5

what type of membrane is the cell membrane

Answer 5

partially permeable

Question 6

what’s a partially permeable membrane

Answer 6

a membrane that allows only certain substances to pass through

Question 7

what will happen if animal cells are surrounded by a hypotonic solution

Answer 7

they will swell and possible burst as water moves into cell by osmosis

Question 8

what will happen if the solution around animal cells is a hypertonic solution

Answer 8

shrink due to water moving out the cell
