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) Rheo leaves are boiled in water first and then a drop of sugar syrup is put on it.
​(v) Golgi apparatus is removed from the cell.

Answer 1

(i) When dry apricots are left in pure water, the water will enter into the apricots through endosmosis, which will result in swelling of the apricots. These apricots will gradually lose water through exosmosis and shrink when they are transferred to a sugar solution.

(ii) A red blood cell kept in concentrated salt solution will lose water due to exosmosis and will shrink in size.

(iii) The breakdown of the plasma membrane will result in the expulsion or scattering of the cytoplasmic components of the cell.

(iv) When rheo leaves are boiled in water, the leaf cells die and are unable to perform osmosis. Thus, the introduction of these boiled leaves into sugar syrup solution will not induce osmosis.

(v) Golgi apparatus is required for the packaging, storage and transportation of proteins. Thus, removal of Golgi bodies will affect the storage, transport and packaging of proteins.
