What is the difference between fusion, diffusion and osmosis?

Question

Jeremiah Allen · Accepted Answer

Fusion has nothing to do with the processes of diffusion and osmosis.

Diffusion and osmosis are our options. Diffusion can happen with or without a membrane; it is the net movement of a substance down a concentration gradient from a region of higher concentration to a region of lower concentration. Osmosis is the net movement of water #(H_2O)# molecules from a region of less negative water potential to a region of more negative water potential down a water potential gradient through a membrane. There are many different meanings associated with the term "fusion." The most widely used meanings include nuclear fusion, interactions between atoms driven by the four fundamental forces, and the bonding of two similarly structured objects under specific conditions.

undefined Fusion is the merging of two or more substances to form a single, more massive entity. Diffusion is the movement of particles from an area of high concentration to an area of low concentration. Osmosis is the specific type of diffusion involving the movement of water molecules across a semi-permeable membrane.
