In simple terms photosynthesis is the process by which plants harness the energy of light and turn it into energy for growth.

The substances that are used for photosynthesis are carbon dioxide (CO₂), water (H₂O) and light.

The substances produced by photosynthesis are glucose (C₆H₁₂O₆) and oxygen (O₂).

The oxygen is released into the atmosphere as it is not needed by the plant, but the glucose is used as an energy source to enable the plant to grow.

Carbon dioxide plus water plus light equals glucose plus oxygen

Activity

Search on YouTube for videos which show animations of photosynthesis – these can help you to visualise how the process is working.
