Potato starch. Coloured scanning electron micrograph of starch grains isolated from the cells of a potato,Solanum tuberosum. The stored starch grains are called amyloplasts. Starch is synthesised from sucrose,a sugar formed in the leaves during photosynthesis and transported to the tuber (potato) through the phloem (vascular tissue). It is used as a store of energy for the later development of buds on the surface of the potato. Starch is an important food resource for humans,hence the potato's popularity as a crop.
