Starch is an energy source for

• A. Fungi
• B. Plants
• C. Animals
• D. Bacteria

Answer: (B)

Plants store energy in the form of starch, a glucose polymer produced during photosynthesis and stored in plastids such as amyloplasts in roots, seeds, and tubers. This stored starch acts as an energy reserve that the plant can break down into glucose when photosynthesis isn’t active, supplying fuel for growth and maintenance. Fungi and animals use glycogen as their storage carbohydrate, and bacteria typically don’t store starch at all. Because starch is specifically produced and stored by plants to fuel their own metabolism, it is the plant’s energy source.
