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 "[Researchers] observed that chloroplasts in immature leaves, early in the expansion phase, contained on average only 1.5 times more starch granules than the chloroplasts of mature leaves."
