Photosynthesis uses carbon dioxide, water light and chlorophyll to produce glucose and oxygen. They do this by taking in the carbon dioxide (CO2) from the air around it. The plant also needs water (H2O) and light (either from the sun or from other sources such as a light bulb). Most of the plants food is made in the palisade cell, which is in the leaf of a plant. Leaves are perfect for photosynthesis because they are flat and thin providing a large surface area for the absorption of light and gases.
