Answer

Brief Explanations:

  • Spherical - shaped bacteria are called cocci. Vibrio are comma - shaped, bacillus are rod - shaped, and spirillum are spiral - shaped.
  • The outer membrane of Gram - negative bacteria contains lipopolysaccharides. Chitin is in fungal cell walls, teichoic acids are in Gram - positive cell walls, and sterols are not a major component of Gram - negative outer membranes.

Answer:

  • Question 1: D. Cocci
  • Question 2: A. Lipopolysaccharides
