Answer 3

A) Condensation from the refrigerator accumulates in the salad container.
B) The dressing creates a hypertonic solution around plant cells, which causes water to diffuse out of the cell plasmolysing the cells.
C) The dressing creates an isotonic solution around plant cells, which causes water to diffuse into and out of the plant cells making them flaccid.
D) The dressing creates a hypotonic solution around plant cells, which causes water to diffuse into the cell creating an increase in turgor pressure.

Answer 4

the external environment must have been hypertonic to the green leaves of the salad. Therefore water moved out of the cells of the leaves and into the environment.

Answer 5

B) The dressing creates a hypertonic solution around plant cells, which causes water to diffuse out of the cell plasmolysing the cells.
