When you consume starchy foods, you''ll have a sustained energy level over a period of several hours. This is different from sugars, which are simple carbohydrates that give you a quick surge …
Learn MoreStarch acts as a sink for carbon during the day, and as a source of carbon during the night period. (a) In the daytime, fixed CO 2, in the form of soluble sugars, is partitioned between sucrose for export to heterotrophic tissues such as roots or immature leaves (pale green) and transient starch for storage, or assimilation for growth.
Learn MoreStarch is a polymer made by plants to store energy. You see, plants need energy to grow and grow and grow. They use energy from sunlight to make a simple sugar, glucose. Plants make polymers - starch - out of extra glucose, so it''s right there when they need it. Click on the figures to the right and below.
