In green leaves, the light and dark reactions occur in

Options

A. stroma and grana respectively
B. grana and stroma respectively
C. cristae and matrix respectively
D. both occur in cytoplasm

Explanation

**Step-by-Step Solution:**

1. **Identify the Location of Reactions**: In green leaves, both light and dark reactions of photosynthesis occur in the chloroplasts.

2. **Light Reactions**: The light reactions take place in the thylakoid membranes of the chloroplasts, specifically within structures called Grana. Grana contain chlorophyll and are responsible for capturing light energy.

3. **Dark Reactions**: The dark reactions, also known as the Calvin cycle, occur in the stroma of the chloroplasts. The stroma is the fluid-filled space surrounding the Grana and is where the conversion of carbon dioxide into glucose happens.

4. **Conclusion**: Therefore, the light reactions occur in the Grana, while the dark reactions occur in the stroma of the chloroplasts.

**Final Answer**: In green leaves, the light reactions occur in the Grana, and the dark reactions occur in the stroma of the chloroplasts.
