Mitochondria

:)

About it (:

  • Mitochondria are membrane-bound organelles in plant and animal cells that transform energy for the cell.
  • Rod shaped organelles
  • The energy is stored in the bonds of other molecules that other cell organelles can get to easily when they need the energy.
  • Mitochondria occur in different numbers, depending on the function of the cell.
  • Ex. liver cells can have up to 2000 mitochondria.
  • Located in the cytoplasm
  • Involved in the processes of cell division and growth, and cell death
  • They are bounded by a double membrane
  • Each of these membranes is a phospholipid bilayer with proteins embedded into it.
  • Mitochondria are only partially dependent on the cell to replicate and grow.
  • Mitochondria have circular DNA and replicate by a reproductive process called fission
  • Consist of an inner membrane and an outer membrane.
  • Range in size between 1 and 10 micrometers in length.
  • The inner membrane folds over many times (the cristae)
  • The Mitochondria is Eukaryotic
