What will be the direction of movement of water, when solution A having water potential of -9 bars and another solution B of -4 bars is separated by a semi-permeable membrane?
1 B to A
2 A to B
3 Both directions
4 None
Explanation:
Water flows from a region of higher water potential to a region of lower water potential. In this case water will flow from cell \(\mathrm{B}\), which has a water potential of -4 bars to cell \(\mathrm{A}\), which has a water potential of - 9 bars.

In gulf countries, desalination of marine water for domestic consumption is done by:
1 Endosmosis
2 Reverse osmosis
3 Exosmosis
4 Plasmolysis
Explanation:
Reverse osmosis works in the other way by applying pressure to the salted water, which pushes the water molecules to the less concentrate side and produces fresh and clean water to drink.

Assertion : If we apply pressure from above on the water within the thistle funnel we can stop entry of water through osmosis. Reason : The pressure at which entry of water across the permeable membrane stops is called osmotic pressure.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Assertion is true but Reason is false. The pressure at which entry of water across the semi-permeable membrane stops is called osmotic pressure.

Select the correct statement from the following:
1 The net direction and the rate of osmosis does not depend on the pressure gradient nor on concentration gradient.
2 Osmotic potential is positive.
3 More is the solute concentration of solution, more will be the pressure required to prevent water from diffusing in.
4 Osmotic pressure is the negative pressure applied.
Explanation:
More is the solute concentration of solution, more will be the pressure required to prevent water from diffusing in. This is the correct statement.
