Method "Most observations and measurements of starch granules in leaves have been made on a transmission electron microscope (TEM) or light microscope images of sections through mesophyll cells." And flow cytometry
Comments "...starch occupied an average of 15% of the chloroplast volume...Although starch occupied approximately 15% of the volume of chloroplasts of both mature and immature leaves at the end of the day, and daily starch turnover was comparable, the chloroplasts of immature leaves contained more, smaller granules than those of mature leaves."
