Students use the gas sensors to measure the amounts of oxygen and carbon dioxide consumed or produced by a plant during respiration and photosynthesis. They also determine the rate of respiration and photosynthesis in a plant.

In this encyclopedia entry, you will find concise text explaining photosynthesis supplemented by a very detailed diagram of the process.

View a diagram showing the processes of photosynthesis and respiration and how they fit together. Includes a legend.

A simplified definition of photosynthesis along with a diagram of the key elements involved in the process are presented.
