Stroma is the ground matrix of

Options

A. Endoplasmic reticulum
B. Mitochondria
C. Nucleolus
D. Chloroplast

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Stroma":**
- Stroma refers to the colorless ground substance found within certain cell organelles.

2. **Identifying the Location of Stroma:**
- Stroma is specifically found in chloroplasts, which are the organelles responsible for photosynthesis in plant cells.

3. **Function of Chloroplasts:**
- Chloroplasts are involved in the process of photosynthesis, which converts light energy into chemical energy.

4. **Components of Chloroplasts:**
- Within chloroplasts, there are two main parts where different reactions occur:
- **Grana:** This is where the light-dependent reactions of photosynthesis take place.
- **Stroma:** This is where the light-independent reactions (Calvin cycle) occur.

5. **Conclusion:**
- Since stroma is the ground matrix of chloroplasts, the correct answer to the question is **Chloroplast**.

**Final Answer:**
Stroma is the ground matrix of **Chloroplast**.
