Q. No.Examine the figure given below and select the wrong option
1. A - Present in only grana lamellae.
2. B - involves down hill movement of electron in terms of oxidation reduction potential .
3. C - Absorbs 700 nm light.
4. The electrons return back to the reaction center.
The process which makes a major difference between C3 and C4 plants is:
| 1. | glycolysis | 2. | Calvin cycle |
| 3. | photorespiration | 4. | respiration |
| 1. | ATP | 2. | NADH |
| 3. | NADPH | 4. | Oxygen |
| 1. | Green sulphur bacteria | 2. | Nostoc |
| 3. | Cycas | 4. | Chara |
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
'Sun basket' is:
1. The device to utilize sun rays directly to meet the requirement of heat energy
2. The sufficient amount of sunlight stored in a cell
3. A device for taking sunbath
4. All of the above
