Starch grains in potato cells
False-colour scanning electron micrograph of a slice through a raw potato, Solanum tuberosum, showing starch grains, or amyloplasts (red), within their cellular compartments. Due to the angle of sectioning some cells show no starch grains. Starch is synthesised from sucrose, a sugar formed in the leaves during photosynthesis & transported to the tuber (potato) via 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 grains are large (the biggest here being 50 microns across), larger than most plant cells. Magnification: X80 at 6x4. 5cm size

EDITORS COMMENTS
This print showcases the intricate beauty of starch grains within potato cells. In this false-colour scanning electron micrograph, a slice through a raw potato (Solanum tuberosum) reveals the vibrant red amyloplasts, or starch grains, nestled within their cellular compartments. The angle of sectioning offers a fascinating glimpse into the diversity of these cells, with some displaying an absence of starch grains. Starch plays a crucial role in the life cycle of potatoes. It is synthesized from sucrose—a sugar produced during photosynthesis in the leaves—and transported to the tuber via vascular tissue called phloem. Once stored in these large and conspicuous grains, starch becomes an essential energy reserve for future growth and development. Notably larger than most plant cells, some of these remarkable starch grains measure up to 50 microns across. The magnification level employed here—X80 at 6x4.5cm size—allows us to appreciate even the tiniest details present within this botanical wonderland. This image not only serves as a testament to the intricacies of plant structure but also highlights how scientific exploration can unveil hidden marvels that exist beneath our very eyes. Captured by Science Photo Library's talented photographers, this print exemplifies their dedication to showcasing awe-inspiring images from various fields such as botany and cell biology while inviting viewers on an enchanting journey into nature's microscopic realm.
