Biochemistry- Osmosis Quiz
Osmosis is one of the methods through which solvents. This movement involves transferring water from a less concentrated solution to a more robust solution through a semipermeable membrane. Most people confuse it with diffusion, which does not involve movement through a membrane. See how much you understood about osmosis in the class by taking the test below before the test.
- 1.What is osmosis?
- A.
Diffusion of water through a semi-permeable membrane
- B.
When you take water out of a cell
- C.
When you put water into the cell
- 2.When the amount of water in a cell is higher than the amount of solute in a cell it is _______.
- 3.What is active transport?
- A.
Don't know
- B.
No energy required
- C.
Movement of molecules across a semi-permeable membrane against a concentration gradient with a protein
- D.
Movement of molecules across a semi-permeable membrane with a protein
- 4.How is isotonic defined?
- A.
Diffusion of water through a semi-permeable membrane
- B.
When the amount of the solute is higher than the amount of water in a cell.
- C.
When the amount of water and solute in a cell are at equilibrium.
- D.
By active transport
- E.
By passive transport
- 5.What is movement in diffusion based on?
- A.
The speed at which the molecules move.
- B.
No movement.
- C.
Movement is based on kinetic energy (speed), charge, and mass of molecules.
- D.
Don't Know.
- E.
What was the question again?
- 6.Describe a cell that is in an isotonic environment.
- A.
When the amount of water in a cell is higher than the amount of solute in a cell.
- B.
Movement of water across a semi permeable membrane.
- C.
A cell that has an equilibrium of water to solute.
- D.
Don't Know.
- E.
When the amount of water and solute in a cell are at equilibrium.
- 7.If a cell is placed in salt water, water will:
- A.
Leave the cell and the cytoplasm and cell membrane shrink.
- B.
Enter the cell and the cytoplasm and cell membrane expand.
- C.
None of the above.
- 8.The cell wall prevents a plant cell from bursting when placed in distilled water.
- A.
True
- B.
False
