A plant is exposed to increasing light intensity from very dim to bright light, while the carbon dioxide concentration and temperature are kept at an optimum level. What will happen to the rate of oxygen production?
|
|
It will increase exponentially.
|
|
|
It will remain constant.
|
|
|
It will decrease to a minimum level.
|
|
|
It will increase to a maximum level.

Explanation:
Detailed explanation-1: -Expert Answer The CO2 (carbon dioxide) level should be approximately 700 ppm (parts per million), and the light intensity should be around 90% (percent) in the gizmo, to maximize the rate of photosynthesis. One of the crucial components in photosynthesis is carbon dioxide.
Detailed explanation-2: -As carbon dioxide concentrations increase, so too does the rate of photosynthesis until a certain point where the graph levels off. At lower carbon dioxide concentrations carbon dioxide is the limiting factor because an increase in carbon dioxide causes an increase in photosynthesis.
