  3. Mitochondria Mitochondria are tiny bodies of varying shapes (cylindrical, rod-shaped, spherical) and size (0.2mm to 2mm), distributed in the cytoplasm It is bounded by a double membrane envelope. outer membrane is porous. The inner membrane is thrown into folds called cristae.

  4. Mitochondria Outer membrane DNA Intermembrane space Inner membrane Cristae Ribosomes

  5. OCristae provide large surface area for ATP generating chemical reactions. The interior cavity of mitochondria is filled with a proteinaceous (gel like) matrix. Matrix contains a few small sized ribosomes, a circular DNA molecule and phosphate granules. Mitochondria are absent in bacteria and the red blood cells of mammals.

  6. Powerhouse of Cell Known as powerhouse of the cell. Energy required for various chemical activities needed for life is released by mitochondria in form of ATP (Adenosine Triphosphate) molecules. Known as energy currency of the cell. pnocdhanies A wofor. making chemical compounds and for mechanical work.

  7. Functions Sites of cellular respiration. synthesize energy rich compounds(ATP). Have their own DNA and ribosomes , so are able to make their own proteins. Hence known as semiautonomous organelles.
