Question

Assertion (A) : If we put dried raisins in plain water and leave them for some time and then place them into a concentrated solution of sugar or salt, they consequently shrink. Reason (R) : Raisins shrink due to endosmosis. *​

Answer 1

Explanation:

here there are 2 situations.

1st:

when the raisins are put into water. as the raisins have less water, they bulge out.

2nd:

when the bulged raisins are put into a concentrated solution, they shrink, as the solution has less water. so the water from the raisins go out to the solution. this is due to exosmosis or plasmolysis.

so here the answer is,

assertion is true but reason Is false as it is exismosis and not endosmosis.
