Expert Solution & Answer

Summary Introduction

Introduction:

The gram stain test is used to differentiate between the gram-positive bacteria and gram-negative bacteria. The gram-positive bacteria retain the crystal violet stain of the gram stain test. While, the gram-negative bacteria, do not retain the crystal violet stain when discoloring agent is applied to it.

Answer to Problem 1ACQ

Correct answer:

Among the answers given, the correct answer is option (a) the cell wall of gram-positive bacteria us formed only of peptidoglycan.

Explanation of Solution

Explanation/justification for the correct answer:

Option (a) is the cell wall of gram-positive bacteria is formed only of peptidoglycan. The cell wall of gram-positive bacteria is thick as it contains many layers of peptidoglycan. Whereas, the cell wall of gram-negative bacteria is thin layered and is composed of peptidoglycan and other structures. Hence, this option is correct.

Explanation for incorrect answer:

Option (b) is gram-positive bacteria contains an outer membrane. The cell wall of gram-negative bacteria is surrounded by an outer membrane, while there is no outer membrane in gram-positive bacteria. Hence, this option is incorrect.

Option (c) is the cell wall of gram-negative bacteria is thick and that of gram-positive bacteria is thin. Many layers of peptidoglycan make the cell wall of gram-positive bacteria thick, while a single layer of peptidoglycan in gram-negative bacteria makes the cell wall thin. Hence, this option is incorrect.

Option (d) is the cell wall of gram-negative bacteria is made of peptidoglycan and that of gram-positive bacteria is made of phospholipids. The cell wall of gram-positive bacteria does not contain phospholipids. It is made up only of peptidoglycan. On the other hand, the cell wall of gram-negative bacteria contains other structures along with peptidoglycan. Hence, this option is incorrect.

Conclusion

The correct statement is that gram positive bacteria contains only of peptidoglycan. Hence, option (a) is correct.
