BIOXI11: TRANSPORT IN PLANTS

Animal cell and a plant cell are kept in distilled water. The solute concentration is same in both the cells, what do you expect
1 Both plant cell and RBC increase in size
2 Both plant cell and RBC would decrease in size and collapse
3 The plant cell would decrease in size and burst, while the RBC would increase in size
4 The RBC would increase in size and burst, while the plant cell would remain about the same size
Explanation:
When RBC and a plant cell are placed in distilled water, endosmosis takes place. Thus, as a result, \(\mathrm{RBC}\) would increase in size and burst, while the plant cell would remain about the same size because of the presence of rigid cell wall made of cellulose and hemicellulose.

What will happen, if a large amount of water enters in a plant cell?
1 OP increase, TP decrease
2 OP decrease, TP decrease
3 OP decrease, TP increase
4 Water potential of the cell increases simultaneously
Explanation:
Water moves from an area of lower diffusion pressure deficit (DPD) to an area of higher DPD. The value of DPD is calculated as the algebraic difference between osmotic pressure and turgor pressure. In a flaccid cell, the turgor pressure is zero and hence DPD will be equal to the osmotic pressure. As water enters a cell, there is an increase in turgor pressure, as the solution in cell sap turns less concentrated there is a fall in osmotic pressure and consequently the DPD falls. In a fully turgid cell, the value of DPD is equal to zero and turgor pressure is numerically equal to osmotic pressure
