Questions: Do all bacterial cells have the same structures?

Transcript text: Do all bacterial cells have the same structures?

Solution

Step 1: Identify the Components of Gram-Positive and Gram-Negative Cell Walls

The image shows two types of bacterial cell walls: Gram-positive and Gram-negative.
Gram-positive cell walls have a thick layer of peptidoglycan and teichoic acid.
Gram-negative cell walls have a thin layer of peptidoglycan, an outer membrane, lipopolysaccharides, and lipoproteins.

Step 2: Label the Gram-Positive Cell Wall

Step 3: Label the Gram-Negative Cell Wall

The left structure is a Gram-positive cell wall with a thick layer of peptidoglycan and teichoic acid.
The right structure is a Gram-negative cell wall with a thin layer of peptidoglycan, an outer membrane, lipopolysaccharides, lipoproteins, and periplasm.
