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.
Q: What is the DEFINITION of DIFFUSION?
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.

Do you want a simple definition of diffusion or do you want a definition of simple diffusion? Both cases are found in the related questions section below.
diffusion of an idea or innovation that is not suitable for the environment in which it diffused into
Hearth Diffusion is and idea or innovation that spreads outward.
Diffusion current is current that is generated due to the vibration of electrons.
Contagious diffusion is a branch of expansion diffusion. It refers to a cultural trait spreading across a population like a disease.
The definition of apparent diffusion coefficient is a measure of the extent of diffusion of the water molecules that are in tissue. It is a term used in reference to an MRI.
Diffusion refers to the process by which molecules intermingle as a result of their Kineti energy of random motion
I think that it means that you have allot of stuff.
A difference in the concentration throughout space because diffusion doesn't just happen in a cell or aqueous solution by definition diffusion is just from high to low concentration
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.
Fick's laws of diffusion describe diffusion and can be used to solve for the diffusion, the concentration gradient (spatial derivative), or in simplistic terms the concept.
controls what enters and exits membrane by using proteins
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.
The diffusion current in a metal-semiconductor diode is derived based on the assumption that the depletion layer is large compared to the mean free path, so that the concepts of drift and diffusion are valid.
Hierarchical diffusion is the spread of a feature or trend from one key person or node of authority or power to other persons or places.
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.
Main Entry: cultural diffusion Part of Speech:n Definition: in anthropology, the process by which a cultural trait, material object, idea, or behavior pattern is spread from one society to another; also called diffusion
Spread of any cultural trait from one culture to another
Diffusion is per definition a passive transport process.
The spread of and idea through physical movement of people from one place to another
I think you mean Culture Diffusion. It is the spreading of a certain culture through a people.
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.
The spontaneous intermingling of the particles of two or more substances as a result of random thermal action
That's a definition of diffusion.
Diffusion in Biology is when atoms and small molecules move across the cell membrane.
