What does the aqueous fluid between the chloroplast membrane and the grana known as?
food shortages
reduces
fuel webs
stroma
Both chloroplasts and photosynthetic bacteria contain grana, neat stacks of flattened sac-shaped membrane compartments called thylakoids . Thylakoids can be considered a sub-organelle within the chloroplast. Between the chloroplast membrane and the grana is an aqueous fluid known as stroma . Thylakoids, especially the thylakoid membrane, organize patterns of proteins and other molecules which conduct photosynthesis, as shown in Figure below . In addition to enzymes, two basic types of molecules - pigments and electron carriers – are significant in this process.
