"The sun is essential for photosynthesis. Sunlight provides the energy for photosynthesis, a process in which plants use sunlight, water and carbon dioxide to produce oxygen and glucose. The suns ultraviolet radiation helps to energize the reaction centres within a plant’s cells, which drives the photosynthetic process. The suns light also provides the wavelength of light that plants use to absorb and use the energy they need."
