In brief state what happens when

(a) dry apricots are left for some time in pure water and later transferred to sugar solution?


(b) a Red Blood Cell is kept in concentrated saline solution?


(c) the Plasma-membrane of a cell breaks down?


(d) rheo leaves are boiled in water first and then a drop of sugar syrup is put on it?


(e) golgi apparatus is removed from the cell?


(a) When dry apricot is placed in pure water, it gains water and swells due to endosmosis. After that if the swollen apricot is placed in the concentrated sugar solution, it loses water and consequently shrinks again due to exosmosis.


(b) When red blood cells are placed in concentrated salt solution, the water molecule will come out and it will shrink and give a shrivelled appearance (crenation).


(c) Breakdown of plasma membrane will result in death of the cell as protoplasmic structures will get dispersed.


(d) When Rheo leaves are boiled, all the cells of leaves become dead. When sugar solution is added on to the boiled rheo leaves, nothing will happen because liquid cannot pass through dead cell membrane.


(e) If Golgi apparatus is removed from the cell, the most cell activities performed by the Golgi apparatus will not take place.
