Detailed explanation-1: -The outer layer of the bacterial cell is called cell wall, which is composed of a polymer matrix named peptidoglycan. Depending on the structure and the thickness of the cell wall, bacterial cell is classified into two groups: Gram positive and Gram negative bacteria.

Detailed explanation-2: -The cell membrane is also known as the plasma membrane. It is the outermost covering of animal cells.

Detailed explanation-3: -A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid.

Detailed explanation-4: -A cell wall is a layer located outside the cell membrane found in plants, fungi, bacteria, algae, and archaea. A peptidoglycan cell wall composed of disaccharides and amino acids gives bacteria structural support. The bacterial cell wall is often a target for antibiotic treatment.
