Q1. In which part of the chloroplast does the Calvin cycle take place? (2019)

Solution:

The Calvin cycle takes place in the stroma of the chloroplast.

⏱ Time: 0s

Q2. Which of the following wavelengths of light is least effective for photosynthesis? (2020)

Solution:

Green light is least effective for photosynthesis because it is mostly reflected by chlorophyll.

⏱ Time: 0s

Q3. Which of the following processes occurs in the thylakoid membranes? (2020)

Solution:

The light-dependent reactions of photosynthesis occur in the thylakoid membranes.

⏱ Time: 0s

Q4. Which wavelength of light is most effective for photosynthesis? (2020)

Solution:

Blue light is most effective for photosynthesis as it is absorbed strongly by chlorophyll.

⏱ Time: 0s

Q5. What is the significance of the light-independent reactions? (2023)

Solution:

The light-independent reactions, also known as the Calvin cycle, fix carbon dioxide into organic molecules.

Q6. What is the function of NADP+ in photosynthesis? (2019)

Solution:

NADP+ acts as an electron carrier, becoming NADPH during the light-dependent reactions.

⏱ Time: 0s

Q7. Which wavelength of light is least effective for photosynthesis? (2022)

Solution:

Green light is least effective for photosynthesis because it is mostly reflected by chlorophyll.

⏱ Time: 0s

Q8. Which gas is a byproduct of photosynthesis? (2023)

Solution:

Oxygen is released as a byproduct of photosynthesis during the light-dependent reactions.

⏱ Time: 0s

Q9. What is the role of NADP+ in photosynthesis? (2021)

Solution:

NADP+ acts as an electron carrier, becoming reduced to NADPH during the light-dependent reactions.

⏱ Time: 0s

Q10. What is the significance of the light-independent reactions of photosynthesis? (2023)

Solution:

The light-independent reactions, or Calvin cycle, are significant for fixing carbon dioxide into organic molecules.
