Question

How do water molecules move through the cell membrane during the osmosis?

Answer 1

Hint: Reverse Osmosis is a technique used to produce soft water from hard water by using a semipermeable membrane. In the osmosis process water moves from lower concentration solution to higher concentration solution.

Complete answer:
- In the question it is asked how water molecules move through the cell membrane during the osmosis.
- Small molecules like water and carbon dioxide will pass directly through the semipermeable membrane because of their neutral nature.
- The mobility of water through the membrane from low concentration to high concentration is called osmosis.
- In osmosis once the concentration of the solutions on the both sides of the membrane reaches same or equal then the flow of water will stop moving from one side to other side through the semipermeable membrane.
- The movement of water molecules through the semipermeable membrane depends on the concentration gradient.
- If the concentration of the solutions is different on both sides of the membrane then osmosis occurs.
- Therefore the water molecules move through the semipermeable membrane during the osmosis due to the concentration gradient.

Note: The passage of water molecules through the semipermeable membrane depends on the composition of the membrane. If the membrane contains high concentration of the cholesterol then the water won’t pass easily through the membrane and the membrane contains less cholesterol than the water molecules will pass easily.
