Diffusion is the tendency of particles in a gas or liquid to become evenly distributed by moving from areas of greater concentration to areas of lesser concentration. Diffusion is driven by the kinetic energy of particles that is a consequence of temperature. It is an inherently random process and particles continue to spread out until they are evenly distributed within the enclosed area.
Biologically, diffusion is the cause of random movement or net movement of particles from an area of high concentration towards an area of low concentration. Osmosis refers to the flow of particles across a membrane. When active transport is absent, diffusion provides the driving force for osmosis across a fully permeable or partially permeable membrane.
Fully permeable: all particles can move through.
Partially permeable: only certain particles an move through.
Active transport: biochemical processes expend energy to move particles.
Note: Reverse osmosis is basically filtering. Pressure is greater on one side of a partially permeable membrane pushing particles through it.
osmosis is passive transport of water molecules across a selectively permeable membrane.
diffusion is the passive transport of any molecules across a selectively permeable membrane.
Osmosis is the diffusion of water.
osmosis is diffusion through a membrane
Osmosis is the diffusion of water across the cell membrance
There has to be a difference in concentration in order for diffusion and osmosis to occur.
osmosis is to do about plants so it is diffusion hope this helped
Osmosis is the diffusion of water.
osmosis is diffusion through a membrane
Diffusion and osmosis are passive and do not require energy.
Osmosis is the diffusion of water across the cell membrance
osmosis
Facilitated Diffusion
diffusion and osmosis are types of ways to get materials into or out of a cell
There has to be a difference in concentration in order for diffusion and osmosis to occur.
Diffusion, Osmosis
There are three forms of passive transport, or the movement of biochemical and other atomic or molecular substances across the cell membranes. They are: osmosis, simple diffusion or facilitated diffusion, and filtration.
osmosis is a form of diffusion. in regard to water, the diffusion type would be osmosis
osmosis is the movement of water across the plasma or cell membrane
