• A

• B

• C

• D

The diagram shows a root hair surrounded by a dilute solution of mineral ions. Which statement describes what happens?

• A Water molecules move into the root hair because the water potential is lower inside.

• B Water molecules move into the root hair because the water potential is lower outside.

• C Water molecules move out of the root hair because the water potential is lower inside.

• D Water molecules move out of the root hair because the water potential is lower outside.

The diagram represents three animal cells, G, H, and I. Each cell has oxygen molecules both inside and outside of the cell. Oxygen molecules move into and out of the cells by diffusion. Which row gives the direction of movement of the oxygen molecules for each cell?

• B no change observed into the cell out the cell

• C no change observed out of the cell into of the cell

• D out of the cell into the cell no change observed

The diagram shows the result of an experiment. The liquid in the glass tube had risen to point X after several hours. Which of the following can be changed to result in a liquid level higher than X?
