WebJul 6, 2024 · Starch is composed of two glucose polymers, amylopectin and amylose, which are arranged in insoluble, semicrystalline granules. Starch synthesis in green plants is confined to the plastids, and in Arabidopsis thaliana leaves, a typical chloroplast contains five to seven starch granules ( Crumpton-Taylor et al., 2012 ). WebNov 13, 2024 · Leaf chloroplasts typically contain multiple lenticular starch granules that form between the thylakoid membranes. These semicrystalline, insoluble granules are …
