Mitochondria in the living cell can readily be identified from other organelles of the cell through a light microscope by using:

Folding of the inner membrane of mitochondria are called

The prokaryotic origin of mitochondria was proposed by

Assertion : Mitochondria and chloroplasts are semi-autonomous organelles.
Reason : They are formed by division of preexisting organelles as well as contain $DNA$ but lack protein-synthesizing machinery.

Organelles which are regarded as the $Power house$ of the cell and in which the oxidative reactions of the respiratory process take place are
