Mitochondria
Mitochondria are round "tube-like" organelles that provide energy to a cell in the form of ATP (Adenosine Triphosphate) for performing different chemical activities for the sustainance of life.
The mitochondria is also called powerhouse of the cell.
It is surrounded by two membranes.
The outer membrane is porous wherea the inner membrane has deep folds that provides a large surface to perform the chemical reactions required for the generation of ATP.
The inner membrane is compartmentalized into various cristae.
The ground substance or space enclosed by inner membrane is called matrix.
Mitochondria have their own DNA and ribosomes and are hence capable to produce some of their required proteins all by themselves.
