Study Notes

Mitochondria in Eukaryotic Cells

  • The primary function of mitochondria is to generate energy for the cell through a process called cellular respiration, producing most of the energy that the cell needs to function.

History of Mitochondria

  • The term 'mitochondrion' was coined by Carl Benda in 1898.

Nickname of Mitochondria

  • Mitochondria are often referred to as the 'powerhouses' of the cell due to their role in generating energy.

Exception to Mitochondria Possession

  • There is one known eukaryotic organism, Monocercomonoides, that has completely lost its mitochondria.

Mitochondria Size

  • The approximate size range of mitochondria in cross section is 0.5-1.5 μm in diameter.
