1. | the CO2 compensation point is more |
2. | CO2 generated during photorespiration is trapped and recycled through PEP carboxylase |
3. | The CO2 efflux is not prevented |
4. | They have more chloroplasts |
1. | high energy bonds are formed in mitochondrial proteins |
2. | ADP is pumped out of the matrix into the inter-membrane space |
3. | a proton gradient forms across the inner membrane |
4. | there is a change in the permeability of the inner mitochondrial membrane toward Adenosine Diphosphate (ADP) |
Cyclic -photophosphorylation results in the formation of:
1. NADPH
2. ATP and NADPH
3. ATP, NADPH, and O2
4. ATP
Stroma in the chloroplasts of higher plants contains:
1. | light-independent reaction enzymes |
2. | light-dependent reaction enzymes |
3. | ribosomes |
4. | chlorophyll |
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 |
1. | secondary growth | 2. | disease resistance |
3. | reproduction | 4. | conserving water |
The correct sequence of cell organelles during photorespiration is:
1. chloroplast-Golgi bodies-mitochondria
2. chloroplast-rough endoplasmic reticulum-dictyosomes
3. chloroplast-mitochondria-peroxisome
4. chloroplast-vacuole-peroxisome
1. | C4 | 2. | CAM |
3. | Nitrogen –fixer | 4. | C3 |
Water-soluble pigments found in plant cell vacuoles are:
1. | chlorophylls | 2. | carotenoids |
3. | anthocyanins | 4. | xanthophylls |
1. | Green sulphur bacteria | 2. | Nostoc |
3. | Cycas | 4. | Chara |
