Explanation / Answer

1)- option a us correct because the opening and closing of stomata depends on the need of carbon dioxide.

2)-option a and d are correct because as we add solute the water potential is lower. And in hypertonic solution cell is plasmolysed.

3)- option b is correct because salt in soil pull water out of the cell and dehydrate the plant.

4)-option c is correct because in transpiration water moves by xylem vessels.
