Biology

Typically, the contents of eukaryotic cells (unlike those of the much smaller prokaryotic cells) are continually mixed by the active process of "cytoplasmic streaming".

Water, dissolved gases, and other materials are typically exchanged through a cell membrane via simple diffusion or via "passive" or "active" transport (both forms of transport employing proteins embedded within the membrane, the active form also requiring the biochemical expenditure of energy).
