Which of the following bacteria have more lipids in their cell wall?

Explanation

Gram-negative bacteria have a more complex cell wall structure compared to gram-positive bacteria. The outer membrane of gram-negative bacteria contains lipopolysaccharides (LPS), which are lipid-rich molecules. This presence of LPS contributes to a higher lipid content in the cell wall of gram-negative bacteria. In contrast, gram-positive bacteria have a simpler cell wall structure with a thicker layer of peptidoglycan and fewer lipids.
