馬鈴薯俗稱洋芋，是全世界常見的美味塊莖食物。切塊烹調時，常會在手中殘留澱粉顆粒粉末，究竟這些美味的粉末藏在哪裡？使用小刀將洋芋切薄片，以甲基藍稍微染色後，放在顯微鏡下觀察，這些澱粉顆粒就如同盛產的玉石般，規則且美麗地綻放在塊莖的薄壁細胞中。

The potato is among the most common tubers in the world. If you cut a potato into pieces and cook it, starch granules appear. Where do these tasty starch granules come from? A small knife was used to cut a potato into thin slices, which were lightly stained with methyl blue and observed under a microscope. These starch granules appear like pieces of jade, arranged neatly and beautifully inside the thin-walled cells of this tuber.
