Chlorophyll is found in the thylakoid membranes. Thylakoids function in the steps of photosynthesis that initially convert light energy to chemical energy. Space inside the thylakoid. Viscous fluid outside the thylakoids. Those steps that use chemical energy to convert carbon dioxide to sugar occur in the Srtoma.
Chloroplasts are one of several types of specialized plant-cell structures called plastids.
There are several forms of chlorophyll.
