Two cells A and B are contiguous . Cell A has osmotic pressure 10 atm, turgor pressure 7 atm and diffusion pressure deficit 3 atm, cell B has osmotic pressure 8 atm, turgor pressure 3 atm and diffusion pressure deficit 5 atm. The result will be
1 Movement of water from cell B - A
2 No movement of water
3 Equilibrium between the two
4 Movement of water from cell A-B
Explanation:
The water moves from lower DPD to higher DPD i.e., from cell A to B. This is because when a cell is placed in pure water, the water enters into the cell as a result of the diffusion pressure deficit (DPD) of the cell sap. DPD= OP- TP

Assertion : When water flows into the cell and out of the cell are in equilibrium. Reason : The cell is said to be flaccid.
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:
A plant cell in an isotonic solution such that the plasma membrane is not pressed tightly against the cell wall, and therefore, is neither swollen (turgid) nor plasmolyzed. When the amount of water entered and expelled out are same it is referred as flaccid cell

If the osmotic pressure of cytoplasm in a cell is balanced by external solution, the solution must be
1 Isotonic
2 Hypertonic
3 Hypotonic
4 All are correct
Explanation:
If an external solution balances the osmotic pressure of the cytoplasm, then it is known as isotonic solution. When the cells are placed in isotonic solution, there is no net flow of water.
