1.1. Figure 1 shows two plant cells.

Figure 1

Which of the plant cells above was placed in a solution with a lower solute concentration than the cell contents?

1.2. Explain what has happened to the plant cell you identified in part (a).

1.3. When placed in different solutions, animal cells will also change.

Figure 2 below shows a red blood cell.

Figure 2

Describe what would happen if a red blood cell was put into a solution with a lower solute concentration than the cell contents and explain why this would be different from what would happen to a plant cell.

1.4. Hereditary spherocytosis is a rare inherited condition that produces red blood cells with an abnormal spherical shape, as shown in Figure 3.

Figure 3

Suggest the possible impact of this condition on a sufferer.
