Stomata help in exchange of gases, which is intake of carbon dioxide and release of oxygen in the presence of water and sunlight by the process of photosynthesis. C 6 H 12 O 6 – Glucose. Answer : The difference is given below. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. This reaction results in the formation of 12 molecules of phosphoglyceric acid (PGA). This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products. Plants absorb carbon dioxide from the air and release oxygen. Biology. Name the organisms that make up each. Log in. It produces glucose, and oxygen as a by-product.
