WebThe cell protoplasm ( cytoplasm) is surrounded by the plasma membrane, a cell wall and a capsule. The cell wall itself is a layered structure in Gram-negative bacteria. All cells have a membrane, which is the essential and definitive characteristic of a "cell". Almost all procaryotes have a cell wall to prevent damage to the underlying protoplast . WebWhile the bacterial and plant cells have a cell wall surrounding the plasma membrane, the animal cells only have a plasma membrane. This plasma membrane in most animal cells is protected by a cell coat.
