The cell was is a structure associated with plant and prokaryotic cells. The cell wall is a thick, rigid mesh of fibers that;

  • surrounds the outside of the plasma membrane

  • protects the cell

  • helps maintain the cell's shape

  • gives the cell support

The Plant Cell Wall

Rigid cell walls allow plants to stand at various heights-- from blades of grass to California redwood trees. Plant cell walls are made of a carbohydrate called cellulose, which gives the cell walls their inflexible characteristics.

Prokaryote Cell Wall

Prokaryotes, such as bacteria, also have a cell wall. Its functions are similar to that of the plant cell, (protects it, maintains shape, gives support) however prokaryotic cell walls are not made of cellulose, like plant cells. The prokaryotic cell wall is made of peptidoglycan, which is a combination of disaccharides and peptide fragments. All prokaryotes have peptidoglycan in their cell walls.
