WebbRecall that prokaryotes are divided into two different domains, Bacteria and Archaea, which together with Eukarya, comprise the three domains of life (Figure 3). Figure 3: The three domains of living organisms. Bacteria and Archaea are both prokaryotes but differ enough to be placed in separate domains. 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 …
