parts. THE DIGESTIVE SYSTEM Digestion is a process of breaking down large complex food substances into simple molecules that can be used by each cell. Most of the foods of organisms consist of carbohydrates‚ fats‚ and proteins. Each of these large molecules acted upon by special kinds of digestive systems that speed up digestion by hydrolysis or splitting of molecules. Food also includes smaller molecules such as water‚ minerals and vitamins. DIGESTION IN PLANTS Plants do not have
