Detailed explanation-1: -The cell membrane is surrounded by a cell wall in all bacteria except one group, the Mollicutes, which includes pathogens such as the mycoplasmas. The composition of the cell wall varies among species and is an important character for identifying and classifying bacteria.
Detailed explanation-2: -Gram-negative and mycobacteria have an inner and outer bacteria membrane. As a phospholipid bilayer, the lipid portion of the bacterial outer membrane is impermeable to charged molecules.
Detailed explanation-3: -The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment.
Detailed explanation-4: -Such membrane bound cell organelles are absent in prokaryotic cells like bacteria.
