Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. They do it to make their own food and obtain the materials they need from the air and soil. The glucose is used in respiration, or converted into starch and stored. Oxygen is produced as a by-product.
Temperature, carbon dioxide, concentration and light intensity are factors that can limit the rate of photosynthsis.
During Photosynthsis.....
- Light energy is absorbed by a green substance called cholorophyll which is found in choloroplasts in some plant cells and algae
- This energy is used by converting carbon dioxide (from the air) and water (from the soil) into sugar
