Quantasomes contain

Options

A. 2000 chlorophyll molccules
B. 250 chlorophyll molecules
C. 3500 chlorophyll molccules
D. 30 chlorophyll molecules

Answer

### Step-by-Step Solution:

1. **Understanding Quantasomes**:
- Quantasomes are defined as particles that are associated with the thylakoid membrane in chloroplasts. They play a crucial role in the process of photosynthesis.

2. **Location of Quantasomes**:
- These particles are located in the thylakoid membranes, which are found within chloroplasts. Chloroplasts are the organelles responsible for photosynthesis in higher plants.

3. **Composition of Quantasomes**:
- Each quantasome contains a specific number of chlorophyll molecules. The typical range is between 230 to 250 chlorophyll molecules per quantasome.

4. **Presence of Carotenoids**:
- In addition to chlorophyll, each quantasome also contains about 50 molecules of carotenoids. Carotenoids are pigments that assist in photosynthesis and provide protection against photo-damage.

5. **Pigment Systems**:
- Quantasomes contribute to the formation of two pigment systems known as Photosystem I (PS1) and Photosystem II (PS2). These systems are essential for the light reactions of photosynthesis.

6. **Function in Photosynthesis**:
- The quantasomes are involved in the photochemical reactions that occur during the light-dependent reactions of photosynthesis. This is where light energy is converted into chemical energy.

7. **Conclusion**:
- Therefore, quantasomes contain approximately 230 to 250 molecules of chlorophyll and 50 molecules of carotenoids, forming the two pigment systems (PS1 and PS2) involved in the light reactions of photosynthesis.

### Final Answer:
Quantasomes contain approximately 230 to 250 molecules of chlorophyll and 50 molecules of carotenoids.
