Light is what starts the process of photosynthesis.

Explanation:

Plants use the energy emitted from light. This energy will be used to convert carbon dioxide and water into glucose, a type of carbohydrate, for the plant to use to grow things like leaves and flowers. Oxygen is just a by-product that humans and others happen to benefit from.
