Question

Question 18
Silver nitrate solution is used to study


(a) Endoplasmic reticulum
(b) Golgi apparatus
(c) Nucleus
(d) Mitochondria


Solution

(b) Golgi apparatus

The Golgi stain method is a method of examining the golgi apparatus in the cell. 

The tissue is hardened by keeping it in potassium dichromate, and then immersed in silver nitrate solution. The resulting reaction between potassium dichromate and silver nitrate caused deposits of silver chromate to form on the cell membrane, staining it black. Golgi’s method is unique because only a few random individual cells are left stained, so they stand out from the other, unstained, cells. These stained cells appear as dark silhouettes against a yellow background, for better researching.
