Too much salt is damaging to cells and organisms, so water helps management the salt held in the physique. However, too much water can also be bad for living things (water toxicity), so salts assist to regulate the water concentration. Together, this ratio of salt and water inside and outdoors of the cell results in a managed imbalance referred to as the osmotic potential of the cell. Each residing factor has methods to take care of this osmotic potential within a small vary (osmoregulation, we’ll talk about this in more element quickly).
