Quantasomes are particles found in the thylakoid membrane of chloroplasts in which photosynthesis takes place. An individual quantasome is measured to be about 185 Å long, 155 Å wide, and 100 Å thick. Molecular weight and density measurements have indicated that one quantasome contains 230 chlorophyll molecules.
