Look at leaves of the same plant on the | Class 11 Biology Chapter Photosynthesis in Higher Plants, Photosynthesis in Higher Plants NCERT Solutions

Q7. Look at leaves of the same plant on the shady side and compare it with the leaves on the sunny side. Or, compare the potted plants kept in the sunlight with those in the shade. Which of them has leaves that are darker green? Why?

Light is a limiting factor for photosynthesis. Leaves get lesser light for photosynthesis when they are in shade. Therefore, the leaves or plants in shade perform lesser photosynthesis as compared to the leaves or plants kept in sunlight.

In order to increase the rate of photosynthesis, the leaves present in shade have more chlorophyll pigments. This increase in chlorophyll content increases the amount of light absorbed by the leaves, which in turn increases the rate of photosynthesis. Therefore, the leaves or plants in shade are greener than the leaves or plants kept in the sun.

For question number seven, the last paragraph contradicts with the answer given in the previous question (i.e. number 6). So, do plants become greener in the shade, or do they turn yellow? Because, the previous question's answer states that if the chlorophyll pigments don't receive enough light, then they stop production and break down, hence allowing the xanthophyll and carotenoids to dominate, and turning the leaves yellow; but here it's stating that leaves in the shade will have MORE chlorophyll pigments to compromise for the lack of light. But, aren't they supposed to diminish in sunlight?
