Class 11 Biology - Photosynthesis in Higher Plants

Exercises

1. By looking at a plant externally, can you tell whether a plant is C3 or C4? Why and how?

2. By looking at which internal structure of a plant you can tell whether a plant is C3 or C4? Explain.

3. Even though a very few cells in a C4 plant carry out the biosynthetic - Calvin pathway, yet they are highly productive. Can you discuss why?

4. RuBisCO is an enzyme that acts both as a carboxylase and oxygenase. Why do you think RuBisCO carries out more carboxylation in C4 plants?

5. Suppose there were plants that had a high concentration of Chlorophyll b, but lacked chlorophyll a, would it carry out photosynthesis? Then why do plants have chlorophyll b and other accessory pigments?

6. Why is the colour of a leaf kept in the dark frequently becomes yellow, or pale green? Which pigment do you think is more stable?

7. Look at leaves of the same plant on the shady side and compare it with the leaves on the sunny side. Which of them has leaves that are darker green? Why?

8. Figure 11.10 shows the effect of light on the rate of photosynthesis. Answer the following:

(a) At which point/s (A, B or C) in the curve light is a limiting factor? (b) What could be the limiting factor/s in region A? (c) What do C and D represent on the curve?

9. Give comparison between the following: (b) Cyclic and non-cyclic photophosphorylation
