WebOsmosis is the diffusion of a solvent through a differentially permeable membrane. In biological systems, the solvent will usually be water. Osmosis will occur whenever the water concentrations are different on either side of a differentially permeable membrane. Osmosis can be defined as the movement of water molecules from a higher water ... WebAns:D. Choice A – Osmosis is an example of passive transport, which involves the movement of water across a semi-permeable membrane. Choice B – Exocytosis is an example of active transport that moves large molecules out of the cell to the cell’s exterior. Choice C – Apoptosis is the process of programmed cell death.
