Osmosis + Water potential:

Question 1

What can easily pass through a partially permeable membrane and cannot?

Answer 1

= water molecules can pass freely
= solute cannot- fixedn

Question 2

What is Osmosis?

Answer 2

= movement of water molecules from a region of high water potential and a region of lower water potential through a partially permeable membrane

Question 3

What is water potential?

Answer 3

= water molecules collide with the membrane and these collisions means the water molecules apply pressure to the cell membrane

Question 4

What happens at an equaliberian?

Answer 4

= osmosis stops
= water molecules will still move across the membrane but the same number will move in both direction
= net movement 0

Question 5

What is the highest possible water potential?

Answer 5

= pure water
= 0 kPA
= water potential of any solution has to be < than 0
= negative
