Key Stage 3
Meaning
A Mitochondrion is a part of a cell where respiration takes place.
Function
Mitochondria provide energy to the cell by respiration.
About Mitochondria
- Mitochondria are used to release the energy from food.
- Cells that need more energy have more mitochondria.
- Sperm cells have a lot of mitochondria to provide the energy needed to swim to the egg cell.
- Mitochondria are found in plant cells, animal cells and fungal cells but are not found in Bacteria.

Key Stage 4
Meaning
A mitochondrion is membrane bound organelle found in eukarytotic cells that is the site of respiration.
Function
- Mitochondria provide energy to the cell by aerobic respiration of glucose.
About Mitochondria
- Mitochondria have their own DNA inside them and are roughly the size of a bacterium which suggests they were once an independent organism that migrated into eukaryotic cells.
