Diffusion and Osmosis Quiz

15 Questions

Quiz Description

Osmosis, which refers to the specific movement of water molecules via partially permeable membranes and Diffusion which is the net movement of substances from regions of higher concentration to regions of lower concentrations meaning that diffusion is driven by the action of the concentration gradient. In this gcse Biology quiz, we are going to see how diffusion and osmosis work

You must have tried out this experiment in school. Place kitchen salt (NaCl) in a cavity of a potato tube and place it in water. The potato tuber will shrink as it loses water to the other solution. 

With this said, you can go ahead and test your knowledge with the quizzes that have been brought together for you on this online revision platform. It is important to note that the quizzes on this platform are free of charge. 

Good Luck

The cell wall of a plant cell is removed using an enzyme. What

would happen if this cell is then placed in distilled water?


Correct
  • 1:
    It would take longer for the cell to become turgid.
  • 2:
    Proteins in the cytoplasm would leave through the cell membrane.
  • 3:
    The cell would become smaller as water passes out.
  • 4:
    The cell would burst as water moves into it.
3:

glucose into the villi of a human?


Correct
  • 1:
    Active transport is responsible for uptake of ions by plant and uptake of glucose into the villi
  • 2:
    Active transport is responsible for uptake of ions by plant and osmosis uptake of glucose into the villi
  • 3:
    Diffusion is responsible for uptake of ions by plant and osmosis uptake of glucose into the villi
  • 4:
    Osmosis is responsible for uptake of ions by plant and active transport uptake of glucose into the villi
