WebJun 29, 2024 · To understand this definition, we also need to understand solutions. ... Tonicity is the type of solution that a cell experiences in the extracellular environment, and osmoregulation is how cells ... WebOsmosis. By definition, osmosis is the diffusion of water through a selectively permeable membrane from an area of high water potential (low solute concentration) to an area of low water potential (high solute concentration). Therefore, for osmosis to occur the membrane must be permeable to water but impermeable to the solute, and the ...
