WEBRice has one flower spikelet laterally compressed and two short glumes. The rice grain is enclosed by the lemma and palea, which form the hull. Rice has a 1000-kernel weight of 15–20 g. Rice, after the hull and bran have been removed, contains about 90% starch, 7–8% protein, 0.3–0.5% fat, and 0.2–0.5% fiber.
