ect the best explanation for the oxgen production leveling off as the light increases in intensity. More light reduces the activity of the chlorophyll by breaking the pigment down. More light prevents water from getting to the leaf cells to be split. Higher light intensity has less blue and red wavelengths Photosystem l and II in the light dependent reactions have a maximum limit on how many light photons they can capture their chlorophyl pigments. Photons hitting the chlorophyll after this limit has been reached cannot be used by the light reaction.

1. Pmax: The maximum pressure of oxygen gas.
2. Arbitrary units: The use of this term mean the graph is not using specific units as labels. Light
intensity could be measured in lumens and oxygen production could have been measured in
mm of Hg
