The photosynthetic unit having 250 chlorophyll molecules is called

Options

A. Photon
B. Quantum
C. Quantasome
D. Oxysomes.

Answer

To answer the question, "The photosynthetic unit having 250 chlorophyll molecules is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the specific term used to describe a photosynthetic unit that contains 250 chlorophyll molecules.

2. **Identifying Key Terms**: The key terms in the question are "photosynthetic unit" and "250 chlorophyll molecules."

3. **Recalling Relevant Information**: In plant cells, chlorophyll molecules are organized into structures that facilitate photosynthesis. One of these structures is known as a quantasome.

4. **Defining Quantasome**: A quantasome is a photosynthetic unit that typically contains around 250 chlorophyll molecules. It is located in the thylakoid membranes of chloroplasts.

5. **Eliminating Incorrect Options**:
- Photon: A photon is a particle of light, not a photosynthetic unit.
- Quantum: This term refers to a discrete quantity of energy, not specifically related to chlorophyll.
- Auxosome: This term is not related to photosynthesis or chlorophyll.

6. **Conclusion**: Based on the information, the correct answer is that the photosynthetic unit having 250 chlorophyll molecules is called a **quantasome**.

### Final Answer:
The photosynthetic unit having 250 chlorophyll molecules is called a **quantasome**.
