WebFeb 17, 2024 · Figure 8.4. 2: In cells that lack a cell wall, changes in osmotic pressure can lead to crenation in hypertonic environments or cell lysis in hypotonic environments. Figure 8.4. 3: In prokaryotic cells, the cell wall provides some protection against changes in osmotic pressure, allowing it to maintain its shape longer. WebHypersaline environments such as salt lakes of evaporitic pools of sea water are commonly inhabited by archaea of the order Halobacteriales (Oren, 2002).Extremely halophilic archaea can bloom at halite concentrations up to saturation levels.
