Questions & Step-by-Step Solutions

Which of the following is a characteristic feature of Gram-negative bacteria?
Correct Answer: Outer membrane with lipopolysaccharides
  • Step 1: Understand that bacteria can be classified into two main groups: Gram-positive and Gram-negative.
  • Step 2: Learn that the classification is based on their cell wall structure and how they react to a staining process called Gram staining.
  • Step 3: Identify that Gram-negative bacteria have a unique outer membrane that is not found in Gram-positive bacteria.
  • Step 4: Recognize that this outer membrane contains molecules called lipopolysaccharides (LPS).
  • Step 5: Conclude that the presence of the outer membrane and lipopolysaccharides is a key feature that distinguishes Gram-negative bacteria from Gram-positive bacteria.
