Answer: Option A
Solution
Answer: Option A
Solution:
a. Solute potential is also called osmotic potential. It is the pressure that needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane.b. Pressure potential is also called turgor pressure. Turgor pressure is the hydrostatic pressure over ambient atmospheric pressure which can build up in living, walled cells.
c. Hydrophilic colloids lead to Imbibition. Hydrophilic colloids contain an outer shell of groups that interact favorably with water, thus causing cells to retain water and imbibe.
d. Exosmosis leads to plasmolysis. Exosmosis is the process by which water molecules flow out of the cell and over the cell membrane, and leads to shrinkage or plasmolysis of a cell.
