Detailed explanation-1: -During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).

Detailed explanation-2: -When carbon dioxide reacts with water, carbonic acid is formed, from which hydrogen ions dissociate, increasing the acidity of the system.

Detailed explanation-3: -The reactants for photosynthesis are light energy, water, carbon dioxide and chlorophyll, while the products are glucose (sugar), oxygen and water. The reactant water molecule is taken up from the soil by the roots for splitting and producing oxygen.

Detailed explanation-4: -During photosynthesis, light energy (sunlight) combines with the reactants-water and carbon dioxide-to form new products: glucose (sugar) and oxygen.

Detailed explanation-5: -Reactants of Photosynthesis Notice that it takes six molecules of water and six molecules of carbon dioxide to make one molecule of glucose. The inputs and outputs of photosynthesis are shown in the diagram at right. Carbon dioxide in the air enters a plant through its leaves.
