Making the world better, one answer at a time. The two structures that surround the prokaryotic cell are the cell membrane or plasma membrane and the cytoskeleton.owever plant cells, in addition to the cell membrane also have the cell wall outside the cell membrane. This provides mechanical rigidity to the cell and prevents the flow of larger particles.
Other prokaryotes have only a plasma membrane. Prokaryotic cells are also surrounded by a cell wall composed of peptidoglycan (amino acids and sugars). Some eukaryotic cells also have cell walls, but none that are made of peptidoglycan.ther prokaryotes have only a plasma membrane.
