Which of the following bacteria have more lipids in their cell wall?
Correct answer: B. Gram-negative bacteria have more lipids in their cell wall
- A. Gram-positive bacteria have more lipids in their cell wall
- B. Gram-negative bacteria have more lipids in their cell wall
- C. Lipids are absent in the cell wall of both gram-positive and gram-negative bacteria
- D. Both have equal amounts of lipids
Explanation
Gram-negative bacteria have a unique cell wall structure that includes an outer membrane rich in lipopolysaccharides (LPS), leading to a higher lipid content compared to gram-positive bacteria. Gram-positive bacteria have a thick peptidoglycan layer but lack this lipid-rich outer membrane, resulting in a lower lipid content. Therefore, the correct answer is that gram-negative bacteria have more lipids in their cell wall. Options suggesting equal lipid content or no lipids in either type are inaccurate, as they misrepresent the structural differences in bacterial cell walls.
