In bean seeds the food store contains an insoluble carbohydrate. The seedling uses the food store for growth.
Name the carbohydrate present in seed.
Here u must also explain how the seedling uses this carbohydrate as it grows.
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.
