Q. By looking at a plant externally can you tell whether a plant is C3 or C4? Why and how?
Solution: C3 plants include sunflower, wheat, spinach, cotton and sugarcane, and C4 plants include pineapple, amaranth, maize, etc. Both categories of plants include crop plants, fruits, and flowering plants, which makes it very difficult to distinguish between C3 and C4 plants by only looking at the external appearance.
Q. Why is the color of a leaf kept in the dark frequently yellow, or pale green? Which pigment do you think is more stable?
Solution: When leaves are kept in dark, then the photosynthesis stops the green-colored chlorophyll molecule is degraded in the absence of light. The accessory pigments such as xanthophyll and carotenoids become prominent, which are yellow in colour; hence, the colour of leaves changes into yellow from green.
Q. 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?
Solution: The chlorophyll content will be more in the shady side of the leaves because the side of the leaf not exposed in sunlight will have more aggregation and concentration of chlorophyll molecule hence it is darker. whereas the leaves exposed in sunlight will lose chlorophyll due to photo-oxidation of the chlorophyll molecule; hence the leaf exposed in sunlight will have a lighter color.
