1. (Science: biology) The movement of necessary substances throughout the cell or organsim.
2. (Science: radiobiology) refers to processes which cause heat energy, or particles, or something else, to flow out of the plasma and cease being confined. diffusion partly determines the rate of transport. Energy losses from a plasma due to transport processes are a central problem in fusion energy research.
See: classical transport, neoclassical transport, anomalous tranport, diffusion, ambipolar diffusion, bohm diffusion, classical diffusion, neoclassical diffusion, anomalous diffusion, energy transport, ripple transport. Something that serves as a means of transportation.An exchange of molecules (and their kinetic energy and momentum) across the boundary between adjacent layers of a fluid or across cell membranes.The movement of a given structure from one location to another.
