Slide 8 - Quizvraag

A single plant cell is placed in an isotonic solution. Salt is then added to the solution. Which of the following would occur as a result of the salt addition?
A
The added salt would enter the cell, causing the cell to take up water and swell.
B
Water would enter the cell by osmosis, and the cell would swell.
C
Water would leave the cell by osmosis, causing the volume of the cytoplasm to decrease.
D
There would be no osmotic movement of water in response to the added salt.

Slide 13 - Quizvraag

If a red blood cell and a plant cell were placed in seawater, what would happen to the two types of cells?
A
The red blood cell would burst, and the plant cell would shrink.
B
Both cells would lose water; the red blood cell would shrivel, and the plant plasma membrane would pull away from the cell wall.
C
Both cells would gain water by osmosis; the red blood cell would burst, and the plant cell would increase in turgor pressure.
D
The red blood cell would shrink, and the plant cell would gain water.

Active transport
  • The cell invests energy 
  • Often against the concentration gradient 
  • For example:
       -Pumps in the membrane
       -Endocytosis
