Which cell organelle is known as "powerhouse of the cell"?

Options

A. Mitochondria
B. Lysosome
C. Golgi apparatus
D. Endoplasmic reticulum

Explanation

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks which cell organelle is known as the "powerhouse of the cell."

2. **Analyze the Options**: The options provided are:
- Option 1: Mitochondria
- Option 2: Lysosome
- Option 3: Golgi apparatus
- Option 4: Endoplasmic reticulum

3. **Evaluate Each Option**:
- **Option 1: Mitochondria**: This organelle is responsible for cellular respiration, a process that produces ATP (adenosine triphosphate), which is the energy currency of the cell. Therefore, this option is likely correct.

- **Option 2: Lysosome**: These organelles are known as "suicidal bags" because they contain enzymes that digest waste materials and cellular debris. They do not produce energy, so this option is incorrect.

- **Option 3: Golgi apparatus**: This organelle is involved in the packaging and distribution of proteins. It does not play a role in energy production, making this option incorrect.

- **Option 4: Endoplasmic reticulum (ER)**: The ER is involved in the synthesis of proteins and lipids. It does not produce energy, so this option is also incorrect.

4. **Conclusion**: After evaluating all the options, it is clear that the correct answer is **Mitochondria**, as it is known as the "powerhouse of the cell" due to its role in producing ATP during cellular respiration.

**Final Answer**: Mitochondria
