Bacteria will not remains alive and grow if they looses its

Options

A. Flagella
B. Cell wall
C. Capsule
D. Envelope

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which component, when lost, would prevent bacteria from remaining alive and growing.

2. **Analyzing the Options**:
- **Option 1: Flagella**: Flagella are tail-like structures that help bacteria move towards nutrients and away from harmful substances. They are crucial for mobility and survival.
- **Option 2: Cell Wall**: The cell wall provides structural support and protection to bacteria. While important, bacteria can survive without it for a time, especially if they are in a suitable environment.
- **Option 3: Capsule**: The capsule is a protective layer that can help bacteria evade the immune system. However, it is not essential for survival or growth.
- **Option 4: Envelope**: The cell envelope, which includes the cell membrane and cell wall, is important for maintaining the integrity of the cell but is not the sole factor for survival.

3. **Determining the Correct Answer**: Among the options, flagella are essential for the movement and nutrient acquisition of bacteria. Without flagella, bacteria would struggle to find food and escape harmful conditions, leading to their inability to survive and grow.

4. **Conclusion**: Therefore, the correct answer is **Option 1: Flagella**.
