Plant cells store fat in

Options

A. Peroxisome
B. Lysosome
C. Sphaerosome
D. Microsome

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where plant cells store fat. We need to evaluate the given options to find the correct answer.

2. **Evaluating Option 1 - Peroxisome**:
- Peroxisomes are small membrane-enclosed organelles that contain enzymes involved in various metabolic reactions.
- They are not primarily involved in fat storage.
- **Conclusion**: This option is incorrect.

3. **Evaluating Option 2 - Lysosome**:
- Lysosomes are known as the "suicide bag" of the cell because they contain digestive enzymes that break down waste materials and cellular debris.
- They digest excess or worn-out organelles, bacteria, and viruses, but they do not store fat.
- **Conclusion**: This option is also incorrect.

4. **Evaluating Option 3 - Spherosome**:
- Spherosomes, also known as oleosomes, are small cellular organelles found in plant cells.
- They are enclosed by a single membrane and are responsible for the storage and synthesis of lipids (fats).
- **Conclusion**: This option is correct.

5. **Evaluating Option 4 - Microsome**:
- Microsomes are fragments of the endoplasmic reticulum and attached ribosomes obtained through centrifugation of homogenized cells.
- They contain proteins, including cytochrome P450, but they do not function in fat storage.
- **Conclusion**: This option is incorrect.

6. **Final Answer**: Based on the evaluations, the correct answer is that plant cells store fat in **spherosomes**.
