Question

Assess the following statements on the basis of your knowledge of cell organelles and briefly state what happens when
(i) Dry apricots are left for some time in pure water and later transferred to sugаr solution?
2)A red blood cell is kept in concentrated saline solution?
(iii) The plasma membrane of a cell breaks down?​

Answer 1

Answer:

(I)Dry apricots have more solutes than pure water. ... When such apricots are transferred to the sugar solution, then the solution will be the hypertonic bearing high amount of solute. Hence, exosmosis, i.e., water will move from inside to the outside of apricot through the apricot wall. Due to this, apricot will shrink.

(ii)If RBCs are held in a concentrated solution, it is said to be hypertonic since the water flows within the cell. This happens when the concentration of the solution is greater than the concentration of the inside of the cell, which allows RBC to shrink. So, the correct option is A, it will lose water and shrink.

(iii)What would happen if the plasma membrane ruptures or breaks down? Answer: If the plasma membrane ruptures or breakdown then the cell will not be able to exchange material from its surrounding by diffusion or osmosis. Thereafter the protoplasmic material will be disappeared and the cell will die.
