Dicot storage root, SEM
Bildnummer 13765254
| Dicot storage root, coloured scanning electron micrograph (SEM). A fracture through a dicot root showing starch storage The starch grains are within the cellulose cell wall compartments. The stored starch grains are called amyloplasts. Starch is the predominant form of carbohydrate found in a variety of root crops. Starch is synthesized from sucrose, a sugar formed in the leaves during photosynthesis & transported to the root via the phloem. All plant seeds and tubers contain starch that is present as amylose and amylopectin. Starch is an important food resource for humans and is cultivated as a crop.
