Potato starch grains. Light micrograph of a transverse section through a potato (Solanum tuberosum),showing the starch grains. Each starch grain has a central cross called the hilum. The grains are formed inside plastids called leucoplasts,but the type of leucoplast that stores starch is usually called an amyloplast. The outer wall of each amyloplast can be seen as a black outer membrane. On average,20-30 percent of the weight of a potato is starch. Magnification: x7,when printed 10 cm wide | |
