Osmosis

Question 1

Osmosis

What is it?

Answer 1

• movement of water molecule
• high water potential to lower water potential
• through partially permeable membrane
• down water potential gradient

Question 2

high water

Answer 2

water has greater potential energy

Question 3

low water

Answer 3

lower water potential

Question 4

more concentrated solution

Answer 4

more negative the water potential

Question 5

Hypertonic

Answer 5

• solution has higher solute conc. than cell
• if water potential of external solution is lower than inside cell
• water flows out

Question 6

Hypotonic

Answer 6

• solution of lower solute conc. than cell
• if water potential of external solution is higher than cell
• water flows into cell

Question 7

Isotonic

Answer 7

• solution of equal conc. to the cell
• molecules still move in and out
• no net movement
