WebMar 20, 2024 · Passive Transport Definition. Passive transport, also known as passive diffusion, is the passage of an ion or molecule through a cell wall along a concentration gradient, or from a region of high concentration to a region of low concentration. Comparable to transferring from the metro train to the platform or leaving a packed area. WebOct 4, 2024 · Facilitated Diffusion Definition.

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. WebTransport across a cell membrane is a tightly regulated process, because cell function is highly dependent on maintain strict concentrations of various molecules. When a molecule moves down its concentration gradient is it participating in passive transport; moving up the concentration gradient requires energy making it active transport.
