Question

Carbon dioxide in the range
of
is adequate for
photosynthesis.
1. 100 - 200 PPM
2. 200 - 300 PPM
3. 500 - 600 PPM
4. 300 – 400 PPM​

Answer 1

Answer:

Concentration of CO2: Higher carbon dioxide concentration increases the rate of photosynthesis. Normally the carbon dioxide concentration of 0.03 to 0.04 percent is sufficient for photosynthesis. Temperature:An efficient photosynthesis requires an optimum temperature range between 25 to 35oC.
