Introduction:-
Mitochondria unless specifically stained, are not easily visible under microscope.The number of mitochondria per cell is variable depending on the physiological activity of the cells.In terms of shape and size also considerable degree of variability is observed. Typically it is sausage shaped or cylindrical having a diameter of 0.2 micrometre.Each mitochondria is double membrane and the inner membrane dividing it’s lumen distinctively into two aqueous compartments.
