How is the matter different before and after photosynthesis?

Carbon dioxide and water are combined to give glucose in the presence of sunlight and oxygen is given off.

Explanation:

In science, matter is neither created nor destroyed but is changed from one form to another.

Photosynthesis has to do with the combination of water and carbon dioxide in the presence of sunlight to form glucose in the light phase of photosynthesis. The glucose undergoes further reactions in the dark phase of photosynthesis to form complex carbohydrates.

The major changes in matter during photosynthesis are; water and carbon dioxide combine to form glucose and secondarily, complex carbohydrates. Oxygen is given out in the process.
