During the stage of photosynthesis referred to as the light-dependent reaction, 12 molecules of water begin the process of reacting with six molecules of carbon dioxide to produce one molecule of glucose, six molecules of oxygen and six molecules of water.
The plant needs energy all of the time. So, by producing glucose, the plant can store this molecule and then use it to produce energy during the night and over winter when there isn't enough sun to provide good photosynthesis. It is very interesting how photosynthesis and cellular respiration help each other. During photosynthesis, the plant needs carbon dioxide and water-- both of which are released into the air during respiration.
