Hint: The two types of bacteria require different treatment and identification. The bacteria stain differently to the Gram stain. The gram negative is harder to kill than gram positive. It helps the doctors to design the treatment through different antibiotics.
Complete answer:
To solve this question we must know about the structure of the two types of bacteria.
The bacterial cell is a prokaryotic cell which is made up of cell wall, cell membrane. It lacks all the membrane bound organelles.
Cell membrane-It is present in both Gram positive and Gram negative bacteria. It is made up of principally phospholipids and proteins.
Cell wall-The gram positive and gram negative bacteria differ in the composition of the cell wall. The gram positive bacteria have a single layer of thick cell wall which is made up of peptidoglycan, teichoic acid and lipoteichoic acid. The cell wall of gram negative bacteria has a thin peptidoglycan layer with broad periplasmic space. They have lipopolysaccharide at the uppermost external layer and comprises lipids at the inner layer.
Ribosome- The spherical 70s ribosome is present in both gram positive and gram negative bacteria. The main function is protein synthesis.
Mitochondria- It is absent in both gram positive and gram negative bacteria.
Hence, the correct answer is option (B)
Note: The gram positive bacteria stain violet and the gram negative stain red on application of Gram stain. Gram negative bacteria are more harmful as their outermost layer is hidden by slime or capsule. Gram negative bacterias are resistant to antibiotics.
