  • Mitochondria are usually cylindrical.
  • The diameter is 0.2 to 1.0 mm, and the length is 1.0 to 4.1 mm.
  • It is a double membrane structure.
  • The outer and inner membranes divide the lumen of the mitochondrion into two compartments - the outer compartment and the inner compartment.
  • The inner compartment is in the form of several folding called cristae which increase the surface area to trap more light energy.
  • The inner compartment is filled with matrix. The matrix consists of mitochondrial DNA, ribosomes and RNA.
