Photosynthesis is a series of steps for the conversion of light energy into chemical energy by living organisms.

All living plants use light and water to make sugar. Sugar is created in the green parts of a plant and every animal on earth depends on it. Without plants we would have no food to eat or oxygen to breath.

Plants absorb carbon dioxide, pull water up through their roots and use light to make sugar. Plants use the sugar to grow. Plants give off oxygen as a by-product. The green parts of the plant make the sugar and oxygen.
