For 10 points, name this energy storage polysaccharide in plant cells.
Along with a structure called the statolith, this compound names a hypothesis explaining how plants are able to sense gravity. Red algae have the floridian type of this compound, which names a synthase that catalyzes the reaction of ADP-glucose into adenosine diphosphate. The iodine test is used for the detection of this compound, the branched form of which is called amylopectin. The enzyme present in saliva breaks down this compound into maltose, and its animal analog is called glycogen. This polysaccharide has its glucose monomers in the alpha configuration, unlike cellulose. For 10 points, name this energy storage polysaccharide in plant cells.
