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 sugar solution?

(ii) A red blood cell is kept in concentrated saline solution?

(iii) The plasma membrane of a cell breaks down?​

Answer 1

Answer:

(a) Dry apricots when placed in pure water swell due end osmosis (inward movement of water) and later when are transferred sugar solution exosmosis (outward movement of water) occurs and they shrink again.

(b) When a Red Blood Cell is placed in concentrated saline solution exosmosis occurs and the RBCs shrink due to excess loss of water.

(c) Breaking of the plasma membrane leads to the scattering of the ceil organelles as it forms the basic supporting unit of the cell.
