Q.

The dark reaction or Calvin-Benson cycle:

1. Fixes water to make glucose

2. Fixes water to make light

3. Water into oxygen to generate ATP

4. Fixes carbon dioxide to make glucose

Q. The tiny openings in leaves that take in carbon dioxide are:

2. Stomata
3. Phloem
4. Tracheids

Q.

The correct sequence of photosynthesis in green plants is:

1. Splitting of water to H₂ and O₂ → Reduction of CO₂ → Absorption of light by Chlorophyll → Carbohydrate formation

2. Absorption of light by Chlorophyll → Splitting of water to H₂ and O₂ → Reduction of CO₂ → Carbohydrate formation

3. Splitting of water to H₂ and O₂ → Absorption of light by Chlorophyll → Reduction of CO₂ → Carbohydrate formation

4. Absorption of light by Chlorophyll → Reduction of CO₂ → Splitting of water to H₂ and O₂ → Carbohydrate formation

Q. For photosynthesis, green plants harness energy from which of the following sources?

1. Sun
2. Wind
3. Moon
4. Gravity
