Salinity: Definition and Importance to Marine Life

High salinity represents an extreme environment in which relatively few organisms have been able to adapt and survive. Most halophilic and all halotolerant organisms expend energy to exclude salt from their cytoplasm to avoid protein aggregation ('salting out'). To survive the high salinities, halophiles employ two differing strategies to prevent desiccation through osmotic movement of water out of their cytoplasm. Both strategies work by increasing the internal osmolarity of the cell… WebJun 5, 2008 · A plant’s adaptation to its environment is one of the most important issues in evolutionary biology.
