Quantasomes are found in

Options

A. stroma
B. chloroplasts
C. mitochondria
D. cristae

Answer

**Step-by-Step Solution:**

1. **Understanding Quantosomes**: Quantosomes are structures involved in photosynthesis. They play a crucial role in the light reactions of photosynthesis.

2. **Location of Quantosomes**: Quantosomes are specifically found in the thylakoid membranes of chloroplasts. Chloroplasts are the organelles in plant cells where photosynthesis occurs.

3. **Identifying the Correct Answer**: Given the options - stroma, chloroplast, mitochondria, and cristae, we can conclude that the correct answer is chloroplast, as quantosomes are embedded in the thylakoid membranes of chloroplasts.

4. **Additional Information**: Quantosomes are arranged in a para-crystalline array along the surface of the thylakoid discs. They are composed of lipids and proteins and contain various photosynthetic pigments and redox carriers. There are two sizes of quantosomes: smaller and larger.

5. **Final Answer**: Therefore, the correct answer to the question "Quantasomes are found in" is **chloroplast**.
