Starch granules of a modified stem primarily found either in chloroplasts ( leaves) or in specialized amyloplasts.
What are starch granules?
A starch grain is essentially a densely packed storehouse of glucose sugar units.
Many plants store starch grains in underground organs like roots, bulbs, tubers, and rhizomes, in addition to seeds and stems.
Abstract. Starch, the primary storage carbohydrate in plants, is synthesized as semi-crystalline, insoluble granules in plastids. Plants primarily store carbon in the form of starch.
It appears as semi-crystalline granules composed primarily of two glucose polymers, amylose and amylopectin. Starch granules have distinctive internal growth rings.
Granule size and shape can differ depending on the plant organ in which they occur and between species.
Starch is the primary storage carbohydrate in most photosynthetic organisms, allowing carbon and energy accumulation in the form of an insoluble and semi-crystalline particle.
