Question

In brief, state what happen when
(i) Dry apricot are left for some time in pure water and later transferred to sugar solution.
(ii) A red blood cell is kept in concentrated salt solution.
(iii) The plasma membrane of a cell breaks down.
​(iv) Golgi apparatus is removed from the cell.


Solution

(i) In pure water, dry apricots will show endosmosis and absorb water to become swelled. These apricots will lose water through exosmosis in a sugar solution.

(ii) In a concentrated salt solution, a red blood cell will gradually lose water and shrink in size.

(iii) The breakdown of the plasma membrane of a cell will result in the death of the cell and all the cytoplasmic contents will be scattered.

(iv) Boiled Rheo leaves will not be able to show osmosis. These leaves will not perform endosmosis or exosmosis when a drop of sugar is used on these leaves.

(v) Golgi apparatus is required by the cell for different processes such as protein modification and protein sorting. The removal of the Golgi apparatus from the cell will affect these functions.
