Statement A : There is a linear relationship between incident light and \(C{O_2}\) fixation rates at low light intensities Statement B : Light saturation occurs at 1 percent of the full sunlight
1 Statement-A is correct but Statement-B is incorrect
2 Statement-A is incorrect but Statement-B is correct
3 Both the statements are correct
4 Both the statements are incorrect
Explanation:
There is a linear relationship between incident light and \(C{O_2}\) fixation rates at low light intensities. t light saturation occurs at 10 per cent of the full sunlight.

Of the total incident solar radiation the proportion of PAR is
1 About \(60\% \)
2 Less than \(50\% \)
3 More than \(80\% \)
4 About \(70\% \)
Explanation:
Photosynthetically active radiation varies from season to season and the spectral range of solar radiation varies from 400-700 nm, photosynthetic organisms are able to use in the process of photosynthesis the amount which accounts for less than \(50\% \).

In a green leaf, despite the presence of optimal light, optimal \(C{O_2}\) conditions, and suboptimal level of temperature the plant is not photosynthesizing. The leaf will start photosynthesizing __.
1 If given the sub-optimal \(C{O_2}\) conditions
2 If exposed to the sub-optimal level of light
3 If given the optimal temperature
4 All of the above.
Explanation:
Despite the presence of a green leaf and optimal light and \(C{O_2}\) conditions, the plant may not photosynthesise if the temperature is very low. This leaf, if given the optimal temperature, will start photosynthesising.

What will happen if we increase the incident light beyond a point
1 The rejuvenation of chlorophyll and an increase in photosynthesis.
2 The breakdown of chlorophyll and an increase in photosynthesis
3 The breakdown of chlorophyll and a decrease in photosynthesis
4 The rejuvenation of chlorophyll and a decrease in photosynthesis
Explanation:
Increase in incident light beyond a point causes the breakdown of chlorophyll and a decrease in photosynthesis.

What causes the decrease in rate of photosynthesis after exposing plant to higher light intensities?
1 Carotenoids block photosynthesis pathway
2 Destruction of chlorophyll molecule due to photo-oxidation
3 Change in leaf angle
4 Given question is wrong.
Explanation:
On exposure to comparatively higher light intensities, chlorophyll present in mesophyll cells undergoes photooxidation and gets destroyed.
