Question

The fresh grape wrinkles, if kept in salt water because of ……..

A)  endosmosis

B)  diffusion

C)  exosmosis

D)  active transport​

Answer 1

Answer:

The fresh grapes wrinkle if kept in salt water because of OSMOSIS. Explanation: The salt water solution is called as hypertonic solution. When the fresh grapes are placed in such type of solution, movement of water occurs from higher to lower gradient region.

Answer 2

Answer: (a) Exosmosis

Explanation: Osmosis is the process in which the molecules move from a higher concentration to a lower concentration through a semipermeable membrane. The energy which is derived is called osmotic pressure. If grapes are kept in salt water which is more concentrated than the cell sap, exosmosis will take place and grapes form wrinkles.
