Question

does a cellulose cell wall surround both bacterial and plant cell

Answer 1

A cell wall[1] is the wall of a cell in plants, bacteria, fungi, algae, and some archaea. Animal cells do not have cell walls, nor do protozoa. Cell walls protect the cells from damage. It is also there to make the cell strong, to keep its shape, and to control the growing of the cell and plant.

The cell wall is the tough, usually flexible but sometimes fairly rigid layer that surrounds some types of cells. It is outside the cell membrane and gives these cells support and protection, as well as acting as a filter. The cell wall also acts as a pressure vessel, preventing over-expansion when water enters the cell by osmosis.

The material in the cell wall varies. In plants and algae, the cell wall is made of long molecules of cellulose, pectin, and hemicellulose. The cell wall has channels which let some proteins in and keeps others out. Water and small molecules can go through the cell wall and the cell membrane.Around the outside of the cell membrane is the bacterial cell wall. Bacterial cell walls are made of peptidoglycan, which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids.Bacterial cell walls are different from the cell walls of plants and fungi which are made of cellulose and chitin, respectively.

The cell wall of bacteria is also distinct from that of Archaea, which do not contain peptidoglycan. The cell wall is essential to the survival of many bacteria. The antibiotic penicillin is able to kill bacteria by preventing the cross-linking of peptidoglycan and this causes the cell wall to weaken and lyse.The lysozyme enzyme can also damage bacterial cell walls.

Answer 2

yes a bacterial cellulose cell surround both bacterial and plant cell
