Water-soluble pigments found in plant cell vacuoles are:
| 1. | chlorophylls | 2. | carotenoids |
| 3. | anthocyanins | 4. | xanthophylls |
| 1. | secondary growth | 2. | disease resistance |
| 3. | reproduction | 4. | conserving water |
C4-plants are more efficient in photosynthesis than C3-plants due to:
| 1. | higher leaf area |
| 2. | presence of larger number of chloroplasts in the leaf cells |
| 3. | presence of thin cuticle |
| 4. | lower rate of photorespiration |
Stroma in the chloroplasts of higher plants contains:
| 1. | light-independent reaction enzymes |
| 2. | light-dependent reaction enzymes |
| 3. | ribosomes |
| 4. | chlorophyll |
Cyclic -photophosphorylation results in the formation of:
1. NADPH
2. ATP and NADPH
3. ATP, NADPH, and O2
4. ATP
| 1. | Green sulphur bacteria | 2. | Nostoc |
| 3. | Cycas | 4. | Chara |
| 1. | ATP | 2. | NADH |
| 3. | NADPH | 4. | Oxygen |
The process which makes a major difference between C3 and C4 plants is:
| 1. | glycolysis | 2. | Calvin cycle |
| 3. | photorespiration | 4. | respiration |
Examine the figure given below and select the wrong option

3. C - Absorbs 700 nm light.
4. The electrons return back to the reaction center.
In the diagrammatic representation of the Hatch and Slack pathway, A and B respectively represent:
| 1. | Mesophyll cells and Bundle sheath cells |
| 2. | Bundle sheath cells and Mesophyll cells |
