Question:-
Which factor least influences the rate of photosynthesis?
Options :-
A) Atmospheric concentration of carbon dioxide
B) Time of day
C) Number of chloroplasts
D) Concentration of nitrogen in the air
Answer :-
D) Concentration of nitrogen in the air
Explanation :-
- Concentration of nitrogen in air is about 78% and it's insert in nature bez neither the planets nor the animals have the ability to break three bonds of N2 molecule (gas ) so any alterations in its concentration will not make any influence in photosynthesis
- concentration of CO2 make influence in the maximum but it also makes its effect upto some extent and that extent is called the saturation point
- Time of the day is effects like in morning and Evening photosynthesis is very less in comparison to the photosynthesis in afternoon
- Rate of photosynthesis is directly proportional to number of chloroplast as more the number of chloroplast more will be the photosynthesis
