Cell organelle getting stained with redox dye Janus Green is

Options

A. Lysosome
B. Mitochondrion
C. Ribosome
D. Golgi apparatus

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks which cell organelle is stained by the redox dye Janus Green.

2. **Identifying Janus Green:**
Janus Green is a basic dye that acts as a redox indicator. It is known for its ability to change color based on the availability of oxygen.

3. **Function of Janus Green:**
Janus Green is primarily used to stain specific cellular structures, particularly those involved in respiration, as it indicates the oxidative state of the organelles.

4. **Analyzing the Options:**
- **Lysosome:** Known as the "suicidal bag" of the cell, involved in digestion and waste removal.
- **Mitochondrion:** The powerhouse of the cell, responsible for energy production through respiration.
- **Ribosome:** Responsible for protein synthesis.
- **Golgi Apparatus:** Involved in packaging and secretion of cellular products.

5. **Determining the Correct Answer:**
Since Janus Green is specifically used to stain mitochondria due to its role in cellular respiration and its sensitivity to oxygen levels, the correct answer is **Mitochondrion**.

6. **Conclusion:**
Therefore, the organelle that gets stained with the redox dye Janus Green is the mitochondrion.

**Final Answer: Mitochondrion**
