Which of the following would have the least affect on photosynthetic rate?
|
|
increase the temp from 20 C to 30 C
|
|
|
increasing the CO2 from 400 ppm to 600ppm
|
|
|
increasing the light intesity from 40 Watts to 60 Watts
|
|
|
increasing the amount of O2 from 20% to 30% in the air

Explanation:
Detailed explanation-1: -The wavelength of green light is thought to be the least efficient for photosynthesis. If the plants are exposed to green wavelengths during photosynthesis, the rate of photosynthesis will be the slowest.
Detailed explanation-2: -The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
Detailed explanation-3: -Carbon dioxide concentration-Increasing the carbon dioxide concentration increases the rate of photosynthesis because carbon dioxide is a reactant in photosynthesis.
