Question
**Question 11:**  
Gram-negative bacteria have a thick outer membrane and peptidoglycan layer.  

**True or False.** 

*Explanation:*  
This question is about the cell wall structure of Gram-negative bacteria. Unlike Gram-positive bacteria, which have a thick peptidoglycan layer, Gram-negative bacteria have a thin peptidoglycan layer located between the inner cytoplasmic cell membrane and a unique outer membrane. The outer membrane itself is a characteristic feature of Gram-negative bacteria, but it is the peptidoglycan layer that is thinner compared to Gram-positive bacteria.
