Bacterial flagella is composed of _________.

Options

A. Filament, hook & basal body
B. Vesicles , tubules and lamellae
C. Capsule, cell wall, mesosomes
D. Slime layer, hook and cell wall

Answer

**Step-by-Step Solution:**

1. **Understanding Bacterial Flagella**: Bacterial flagella are essential structures that allow bacteria to move. They are considered the organ of locomotion for bacteria.

2. **Identifying the Components**: The bacterial flagellum is a complex structure that consists of three main parts:
- **Filament**: This is the long, whip-like structure that propels the bacterium.
- **Hook**: This connects the filament to the basal body and allows for the rotation of the filament.
- **Basal Body**: This is the anchor that embeds the flagellum in the bacterial cell membrane and is responsible for the movement.

3. **Conclusion**: Given the components identified, the bacterial flagella is composed of the filament, hook, and basal body. Therefore, the correct answer to the question is "filament, hook, and basal body."

**Final Answer**: Bacterial flagella is composed of filament, hook, and basal body.
