- nucleus : DNA localization.
- mitochondria : energy production site.
- endoplasmic reticulum, ribosomes, Golgi apparatus : proteins synthesis.
- lysosome, peroxisome : destruction of damaged or life-ended proteins.
- membrane : barrier between internal (cytoplasm) and external environment of cell et manage exchanges.
