Question

(iv) When you keep raisins in hypotonic solution, endosmosis occurs. It continues till
(a) Cells burst
(b) Cells are fully turgid
(c) Two hours
(d) You keep them in solution​

Answer 1

Answer:

till cell burst

Explanation:

logical

Answer 2

Answer:

It continues till (b) Cells are fully turgid

Explanation:

• A hypotonic (hypo=less) solution refers to a solution whose concentration is less than that of the cell sap which means it contains more water molecules and fewer solutes.

• So when a cell is immersed in such a solution, water will diffuse into the cell(endosmosis) increasing in size.

• Thus when we keep raisins in a hypotonic solution, endosmosis takes place.

• And this continues till the solutions become isotonic i.e. the concentration is equalised on both sides of the raisin cell membrane.

• Thus the entry of water stops (endosmosis) which marks the cells as fully turgid.

Hence option b) is correct.
