RBC
Is the red blood cell (RBC) in a hyper-, hypo-, or isotonic solution? How can you tell?
Is water moving across the RBC membrane? Draw arrows and describe water movement.
What is going to happen to the RBC?
water
solute
You transfer the RBC to pure water (shown here). Is this solution hyper-, hypo-, or isotonic to the cell? How can you tell?
Use the structures on this slide to illustrate how the RBC changes after you transfer it to pure water.
What is going to happen to the RBC? Does it change size? If so, show it by changing the size of the cell. Why does it change this way?
Is water moving across the RBC membrane? If so, move the water molecules to show where they move to and draw arrows. Describe why water moves in this direction.
