What is special about osmosis?

Could you please elaborate on the uniqueness of osmosis? What makes it stand out from other biological processes? Is there a particular aspect of osmosis that's noteworthy, such as its role in cellular homeostasis or its mechanism of action? Additionally, could you explain how osmosis is relevant in the larger context of biology and physiology? I'm particularly interested in understanding its significance and how it contributes to the overall functioning of living organisms.
