Webborganisms within the domains Bacteria and Archaea are based on the prokaryotic cell. Parts and Functions of the Prokaryotic Cell Part Function Capsule Found in some bacterial cells, this additional outer covering protects the cell when it is engulfed by other organisms, assists in retaining moisture, and helps the cell adhere to surfaces and nutrients. WebbIn most prokaryotic cells, morphology is maintained by the cell wall in combination with cytoskeletal elements. The cell wall is a structure found in most prokaryotes and some eukaryotes; it envelopes the cell membrane, protecting the cell from changes in osmotic pressure (Figure 3.15).Osmotic pressure occurs because of differences in the …
