Detailed explanation-1: -All cells are surrounded by a cell membrane or plasma membrane which separates the inner and outer components of the cell. The cell components are suspended in a fluid called cytoplasm. Animals are multicellular organisms. The cells are specialized to perform various functions.

Detailed explanation-2: -The cell membrane (also known as the plasma membrane) is a biological membrane that separates the interior of all cells from the outside environment. Bacteria and plants also have the cell membrane.

Detailed explanation-3: -The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment. In bacterial and plant cells, a cell wall is attached to the plasma membrane on its outside surface.

Detailed explanation-4: -Plant cells do have a cell membrane, as do animal cells. Between the cytoplasm and the cell wall, the cell membrane is present.

Detailed explanation-5: -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.
