What is the process of osmosis?

The process of osmosis specifically refers to the movement of water across a selectively permeable membrane. During osmosis, water moves from an area of higher concentration of water (or lower concentration of solutes) to an area of lower concentration of water (or higher concentration of solutes). This process is essential for maintaining the balance of fluids in biological systems.

In the context of biological membranes, concentration gradients play a crucial role. When there is a difference in solute concentration on either side of the membrane, water will strive to equalize these concentrations by moving towards the area where there are more solutes. As a result, the correct understanding of osmosis reflects the overall tendency for water to migrate in response to solute concentrations, thus helping to maintain homeostasis within cells and organisms.
