Photosynthesis is the process plants use to turn light into energy. Using light, water, and carbon dioxide, the plant makes sugars that fuel growth and release oxygen as a byproduct.
For plant owners, photosynthesis explains why light is essential. More usable light generally means more energy for new leaves, roots, and flowers. When light is too low, the plant cannot make enough energy, which can lead to slow growth, smaller leaves, and yellowing.
