Which factor would not increase the production of glucose by photosynthesis in plants?
|
|
freezing temperatures
|
|
|
extra rainfall
|
|
|
increased carbon dioxide levels
|
|
|
increased sunlight exposure

Explanation:
Detailed explanation-1: -The major limiting factors in this process are light intensity, temperature, and carbon dioxide levels. For both light intensity and temperature, if the level is too low or too high, the rate of photosynthesis declines rapidly.
Detailed explanation-2: -Light dependent reactions use light energy and so are not affected by changes in temperature. As light intensity is increased further, however, the rate of photosynthesis is eventually limited by some other factor. So the rate plateaus.
