淀粉是葡萄糖分子聚合而成的长链化合物,以淀粉粒的形式贮藏在植物的根、茎及种子等器官的薄壁细胞细胞质中。不同种属的植物淀粉具有不同的形态特征,因此根据淀粉粒的形态特征可以进行植物种类的鉴定。淀粉粒可以在地层中长时间保存,科学家曾经从南非一个距今200万年的石器上提取到淀粉粒。此外,淀粉粒还具有产量高的特点,植物种子和果实中均含有丰富的淀粉粒。由于植物中产生淀粉粒的器官与植硅体不同,使淀粉粒较植硅体有一优势,即在一些古人类加工坚果类、块茎类食物或脱壳种子的器物、生产工具等不保存有植硅体的 Starch is a long-chain compound formed by the polymerization of glucose molecules, which is stored in the form of starch grains in the parenchyma cells of the plant such as roots, stems and seeds. Different species of plant starch have different morphological characteristics, so the identification of plant species can be based on the morphological characteristics of starch grains. Starch grains can be preserved in formations for long periods of time. Scientists have extracted starch grains from a 2 million-year-old stone plant in South Africa. In addition, starch grains also have the characteristics of high yield, plant seeds and fruits are rich in starch grains. Because the starch-producing organs in plants are different from phytoliths, starch granules have an advantage over phytoliths. In some ancient human-processed nuts, tubers, or unshelled seeds, utensils, production tools, Silicon body
