Site of Calvin Cycle is -

Options

A. Chloroplast
B. Cytoplasm
C. Mitochondria
D. Glyoxisome

Answer

**Step-by-Step Solution:**

1. **Understanding the Calvin Cycle**: The Calvin Cycle is a series of biochemical reactions that take place in the photosynthetic process of plants. It is primarily responsible for converting carbon dioxide and other compounds into glucose.

2. **Identifying the Location**: The Calvin Cycle occurs in the chloroplasts of plant cells. More specifically, it takes place in the stroma, which is the fluid-filled space surrounding the thylakoids in the chloroplast.

3. **Evaluating the Options**:
- **Option 1: Chloroplast** - This is the correct answer as the Calvin Cycle occurs in the stroma of chloroplasts.
- **Option 2: Cytoplasm** - This is incorrect. The cytoplasm is where various cellular processes occur, but not the Calvin Cycle.
- **Option 3: Mitochondria** - This is also incorrect. Mitochondria are involved in cellular respiration, not photosynthesis.
- **Option 4: Glyoxysome** - This is incorrect as well. Glyoxysomes are involved in the breakdown of fatty acids and not in the Calvin Cycle.

4. **Conclusion**: After evaluating all the options, the correct answer is **Chloroplast** (Option 1), as it is the site where the Calvin Cycle occurs.

**Final Answer**: The site of the Calvin Cycle is **Chloroplast**.
