Starch is a carbohydrate found in many plants, used as a thickening agent in cooking, while flour is a powder made by grinding raw grains or other seeds or roots.

Key Differences

Starch is a polysaccharide carbohydrate consisting of a large number of glucose units, primarily found in plants. Flour, on the other hand, is a powder obtained by grinding grains, nuts, seeds, or roots, and contains starch as one of its components.
