Cell Transport - Osmosis

Question 1

Osmosis

Answer 1

• occurs when molecules in a solution cannot cross the membrane
• water corsses the membrane and changes the concentration of the solution
• Diffusion of water through a selectively permeable membrane
• Movement from an area of high concentration to an area of low concentration.​​
• Why don’t many cells burst?
• Animal cells are usually in an isotonic solution or hypertonic solution where the cell would shrink.
• If they are in a hypotonic solution where water will move into the cell, animal cells have contractile vacuoles to pump water back out using energy.​​
