In bean seeds the food store contains an insoluble carbohydrate. The seedling uses the food store for growth. Name the carbohydrate present in...

Plant seeds store glucose, a carbohydrate, as the polysaccharide starch. Starch can be separated into two fractions--amylose and amylopectin. Natural starches are mixtures of amylose (10-20%) and amylopectin (80-90%).Amylose forms a colloidal suspension in hot water; amylopectin is completely insoluble.

Seedlings use the starch as an energy source for growth until the plant is big and complex enough to photosynthesize.
