What source of energy does a carrot plant use to produce carrot?

Plants use the energy from the Sun to convert carbon dioxide and water into glucose through photosynthesis. Glucose is then used by the plant to produce other organic molecules, such as cellulose, lipids, and proteins. These organic molecules are used to build the plant's structures, such as leaves, stems, and roots, as well as to produce the plant's reproductive structures, such as flowers and fruits.
