Two cells A n B are contignous. cell A has osmotic pressure of 10 atm ...
DPD = OP - TP . And water moves from lower dpd to higher dpd . so option D is correct.
Two cells A n B are contignous. cell A has osmotic pressure of 10 atm ...
Answer:
Introduction:
In this scenario, we have two contiguous cells A and B. Cell A has an osmotic pressure of 10 atm, turgor pressure of 1 atm and DPD of 3 atm. On the other hand, cell B has an osmotic pressure of 8 atm, turgor pressure of 3 atm and DPD of 5 atm. We have to determine the movement of water between the two cells.
Explanation:
Osmotic pressure is the pressure that needs to be applied to prevent the movement of water from a solution. Turgor pressure is the pressure exerted by plant cells against the cell wall. DPD or pressure potential is the difference in pressure between the cell and its surroundings.
Comparison of Osmotic Pressure:
Cell A has a higher osmotic pressure than cell B. Therefore, water will move from cell B to cell A.
Comparison of Turgor Pressure:
Cell B has a higher turgor pressure than cell A. Therefore, water will move from cell A to cell B.
Comparison of DPD:
Cell A has a lower DPD than cell B. Therefore, water will move from cell B to cell A.
Overall Movement of Water:
Taking all the above factors into consideration, we can conclude that water will move from cell B to cell A as the osmotic pressure gradient is stronger than the turgor pressure gradient.
Conclusion:
In conclusion, the movement of water will be from cell B to cell A.
