what is defined as the movement of water across a semipermeable membrane from high concentration to low concentration?
Oliga [24]
<span>Osmosis is defined as the movement of water across a semipermeable membrane from high concentration to low concentration. This occurs when the surrounding environment of the cell has a higher water concentration than the cell itself. Osmosis is important in animal cells because it helps in the distribution of nutrients and the release of metabolic waste products. In plant cells, osmosis is responsible for the absorption of water from the soil and the elevation of the liquid into other parts of the plants.</span>
