Diffusion is one type of passive transport. In Diffusion, molecules move from a higher concentration gradient to a lower concentration gradient. Diffustion does NOT need energy, or ATP.

A: Diffusion- a type of passive transport in cells in which molecules move from areas where there are more of them to areas there are fewer of them.

What is the relation between osmosis and diffusion?

Osmosis is a subset of diffusion. Osmosis is a special type of diffusion. The definition of Osmosis is: the diffusion of water through a semi-permeable membrane. The diffusion process continues for ever but the net effect can be measured and noticed until the diffusion rate in both directions becomes equalized producing a state of diffusion equilibrium.

Can diffusion take place in a solid state?

Diffusion is the movement of molecules through a gradient. A solid state is one where there is no movement of constituent parts. By definition, diffusion cannot take place in a solid state.

Is Diffusion made of small or large molecules?

Diffusion is not a substance. It is a physical process. Diffusion is the process where there is a movement of molecules from where they are abundant to where they are scarce. A more technical definition would be: Diffusion is a process in which molecules move from a region of higher concentration to a region of lower concentration.

What is the definition of migrant diffusion?

Migrant diffusion is a type of diffusion when something is prevalent in its hearth (origin) for a brief period, but then dies in its hearth by the time it spreads outward to other areas. For example, the spread of the flu is migrant diffusion because by the time it spreads away from its hearth, most of the people in its hearth are generally already immune to it.
