Mitochondria

These are the organelles which provide energy to the cell during respiration. Because of this property, these are also called “power house of the cell”.

Shapes

These are spherical or may be rod like in shape

Structure

These are bounded by double membrane. Outer membrane is smooth while inner membrane forms infolding called cristae. Small rounded bodies called elementary particles ranging up to one million in number are parent on inner membrane. These particles involve in respiration. Inside the inner membrane, mitochondria are filled with mitochondrial matrix. Mitochondria have their own DNA and their own Ribosomes.

Functions

Mitohondria extract energy from different components of food and convert it in the form of ATP which is the useable form of energy for cell.
