Describe the structure of mitochondria with the help of a diagram.
. Structure of mitochondria:
- Mitochondria is known as energy currency or power house of cell.
- Mitochondria can be seen with a special microscope called electron microscope.
- Mitochondria are sac-like structures present in the cytoplasm of the cells.
- They may be of various shapes thread-like, spherical.
- Mitochondria have two compartments - an inner compartment and an outer compartment. The substance in the inner compartment is called matrix.
- The matrix is surrounded by a membrane called inner membrane of mitochondria.
- The inner membrane is thrown into several folds called cristae. The cristae extended into the matrix.
- The space between the folds is continuous with the outer compartment.
- The outer compartment is surrounded by another membrane - the outer membrane.
The outer membrane is smooth and has no projections.
- The inner membrane, the matrix and the elementary particles in the mitochondria have large number of enzymes and other required proteins for the respiration and
