The cell wall of a bacterium is surrounded by a capsule which has the purpose of preventing the bacteria from becoming dehydrated. It is usually made up of a layer of polysaccharides and may also contain proteins. The presence of a capsule is usually associated with pathogenic (disease causing) bacteria because it acts as a barrier against white blood cells so that the white blood cells cannot engulf the bacteria and by this bacteria able to cross the defence mechanism of host and cause disease. It can also some time resist antibiotics
Pilli (The small hairlike structures) surround all bacterial cell walls, and also flagella can be protruding one-multiple times based off of what species the bacterial cell is.
No. It is called a "cell wall". The cell membrane is a thin, semi-permeable layer between the cell wall and the cytoplasm.
A type of bacterium that is surrounded by a thick protective membrane is called an endospore. This bacterium can be killed by the use of antibiotics.

A cell wall surrounds and protects a plant cell.
Bacterial cells have a cell membrane, as do the members of all 6 animal kingdoms. However, they do not have a cell wall. The cell wall is used only in plants, to help the plant stand up straight.

the cell wall surrounds the entire cell from the outside
Cell wall
It is first surrounded by cell membrane.After that there is a cell wall.
In plant cells, the cell wall surrounds the cell membrane. The cell wall gives the cell rigidity and strength. Cell walls can also be found in bacteria, fungi, and algae. They are not found in animal cells or protozoa.
This structure is called as Cell Wall that gives shape to the bacteria. This wall gives protection to the bacteria and prevents it from exploding because of osmotic lysis.
