Cell organelle which is called cell engine is :-

Options

A. MItochondria
B. Lysosome
C. Vacuoles
D. Endoplasmic reticulum

Answer

**Step-by-Step Text Solution:**

1. **Identify the Question**: The question asks for the cell organelle that is referred to as the "cell engine."

2. **Review the Options**: The options provided are:
- A) Mitochondria
- B) Lysosome
- C) Vacuoles
- D) Endoplasmic Reticulum

3. **Analyze Each Option**:
- **Lysosome**: Known as the "digestive system" of the cell, it breaks down waste materials and cellular debris but does not produce energy.
- **Vacuoles**: These are storage organelles that hold various substances but are not involved in energy production.
- **Endoplasmic Reticulum**: This organelle is involved in protein and lipid synthesis but is not primarily responsible for energy production.

4. **Focus on Mitochondria**: Mitochondria are known as the powerhouse of the cell because they generate ATP (adenosine triphosphate), which is the energy currency of the cell. They are involved in aerobic respiration and oxidative phosphorylation, making them crucial for energy production.

5. **Conclusion**: Based on the analysis, the cell organelle referred to as the "cell engine" is the mitochondria.

6. **Final Answer**: The correct answer is **A) Mitochondria**.
