Osmosis, the fluid phenomenon responsible for countless slug deaths at the hands of mischievous children, is fundamentally important not only to much of biology, but also to engineering and industry. Most simply put, osmosis refers to the flow of fluid across a membrane driven by a (solute) concentration difference—like water from a salted slug's cells or absorbed by the roots of plants.
