The photosynthetic unit is

Options

A. Glyoxysome
B. Spherosome
C. Microsome
D. Quantasome

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the photosynthetic unit, which is a specific term used in the context of photosynthesis in plants.

2. **Analyzing the Options**:
- **Glyoxysome**: These are specialized peroxisomes found in plants and filamentous fungi, primarily involved in the conversion of stored fats into carbohydrates during seed germination. They are not directly involved in photosynthesis.
- **Spherosome**: Also known as oleosomes, these are involved in the storage and synthesis of lipids. They are not related to the photosynthetic process.
- **Microsome**: This refers to fragments of the endoplasmic reticulum and is involved in steroid synthesis. It does not play a role in photosynthesis.
- **Quantosome**: These are particles located in the thylakoid membrane of chloroplasts where the actual process of photosynthesis occurs.

3. **Identifying the Correct Answer**: Based on the analysis, the quantosome is the only option that directly relates to the photosynthetic process, as it is where photosynthesis takes place in the chloroplasts.

4. **Conclusion**: Therefore, the photosynthetic unit is the **Quantosome**.

**Final Answer**: The photosynthetic unit is the **Quantosome**.
