If the light becomes unavailable during photosynthesis after exposure to sunlight then
1 Biosynthetic process stops immediately
2 Biosynthetic phase does not stop
3 Biosynthetic phase continues for some time and then stops
4 Biosynthetic phase stops forever
Explanation:
If light suddenly becomes unavailable, biosynthetic phase/ dark reaction continues for some time till the available ATP and NADPH is not completely consumed. After the products of light reaction are exhausted, the dark reaction stops.

Which factor affects the photosynthesis?
1 Light quality
2 Light intensity
3 The duration of exposure to light
4 All of the above
Explanation:

At which percentage of the full sunlight light saturation occurs ?
1 10 per cent
2 Less than 2%
3 Less than 5%
4 0.15
Explanation:
Light saturation occurs at 10 per cent of the full sunlight.

How do intermittent light impacts on the rate of photosynthesis?
1 Causes decrease in rate of photosynthesis
2 Causes increase in rate of photosynthesis
3 Rate remains unaffected
4 We can’t predict
Explanation:
Intermittent light is the type of light which is not steady or continuous. Two types of reactions occur in plants that are: light reaction and dark reaction. Light reactions are faster than dark reactions. Due to this ATP and NADPH accumulate in the plants. Reduction of photosynthesis can occur due to this. In case there is an interruption of light ATP andNADPH are fully consumed. Reduction of \(C{O_2}\) leads to the formation of glucose. Thus, rate of photosynthesis increases.
