Net gas exchange 2.40

1. photodynthesis only occurs during the day, however, respiration occurs at all times and in all cells.
2. Also, photossynthesis consists of Carbon dioxide and water to release oxygen and glucose. However, in respiration glucose is broken down in the presence of oxygen.
3. Photosynthesis and respiration work in reverse directions. Equations have reversed arrows. 
4. However the process of photosynthesis and respiration occur at the same time therefore there is a possibilty of them being balanced. 
5. When the use of carbon dioxide and oxygen are balanced, it is called the compensation point. 
6. If light intensity is increased, then the rate of photosynthesis will increase therefore the rate of the production of Oxygen and Carbon Dioxide will increase.
7. The net affect would be the oxygen production. Net oxygen production occurs when there is high light intensity.
8. During the night Net carbon dioxide productions occur through respiration. However, not a lot of Carbon dioxide is produced because the stomatal pores are closed.
