Quantasomes occur on the surface of

Quantasomes occur on the surface of Plasmalemma.
Quantasomes were first identified by Roderic B. Park in 1962.
Quantasomes are particles found in the thylakoid membrane of chloroplasts in which photosynthesis takes place. They are embedded in a paracrystalline array on the surface of thylakoid discs in chloroplasts.
They are composed of lipids and proteins that include various photosynthetic pigments and redox carriers.
