Which part of bacteria is most delicate and can damage bacterial cell immediately?
Correct answer: B. Cell membrane
- A. Cell wall
- B. Cell membrane
- C. Slime layer
- D. Capsule
Explanation
The cell membrane is the most delicate part of the bacterial cell because it is thin and flexible. It plays a crucial role in protecting the cytoplasm and regulating the transport of substances into and out of the cell. Damage to the cell membrane can lead to the immediate death of the bacteria. In contrast, the cell wall, slime layer, and capsule are more robust structures that provide protection and support, but they are not as critical to the cell's immediate survival as the cell membrane.
