Osmosis Scenarios & Cell Membrane Environment Hypertonic or Hypotonic Discussion

I’m studying for my Biology class and need an explanation.

 

1. A red blood cell (0.9% NaCl) is placed into a solution of 20% NaCl. The water is able to mov through the cell membrane, what happens to the red blood cell in this situation? Is this environment (outside solution) that the cell was placed into hypertonic or hypotonic?

2. A red blood cell (0.9% NaCl) is placed into a solution of 100% DI water. The membrane is again permeable to water. What happens to the cell in this situation? Is this environment (outside solution) hypertonic or hypotonic?

3. A plant cell (0.9% NaCl) is placed into a solution of 20% NaCl, the membrane is permeable to water. What happens to the plant cell?

4. A plant cell (0.9% NaCl) is placed into a solution of 100% DI water, the membrane is permeable to water. What happens to the plant cell?

5 A dialysis bag (simulating a membrane) of 15% glucose is placed in a beaker of 5% glucose. The bag is permeable to both water and glucose.

A. What is the net movement of water?

B. What is the net movement of glucose?

C. Which solution in this situation s hypertonic and which is hypotonic?
