WebApr 5, 2024 · Hint: Floridean starch is a type of starch molecule that has a long branched chain as compared to the amylopectin. It is a type of storage glucan. It is stored as grains outside the chloroplast in red algae and glaucophytes. The algae are classified into three groups – Phaeophyceae, Chlorophyceae, and Rhodophyceae. WebJul 7, 2001 · The starch granules from red algae (floridean starch) show structural similarities with higher plant starch granules but lack amylose.
