Which of the following components provides sticky character to the bacterial cell?
Answer: (D) Glycocalyx. Answer: (D) Glycocalyx Solution: The glycocalyx (slime layer/capsule) outside the bacterial cell wall provides the sticky character to bacterial cells.
- A.Cell wall
- B.Nuclear membrane
- C.Plasma membrane
- D.Glycocalyx✓
Correct Answer
(D) Glycocalyx
Solution & Explanation
Answer: (D) Glycocalyx Solution: The glycocalyx (slime layer/capsule) outside the bacterial cell wall provides the sticky character to bacterial cells. This detail on prokaryotic cell envelope (glycocalyx, cell wall, plasma membrane) is developed in the Cell chapter; this chapter introduces bacteria as Kingdom Monera. The cell wall, nuclear membrane and plasma membrane do not give stickiness, so (D) is correct.
