Diffusion is the net movement of particles(atoms,ions or molecules) from a region where are of higher concentration to a region where they are of lower concentration, down a concentration gradient.
Factors that affect the rate of diffusion
1.Temperature
2.the concentration gradient
3.Physical movement
4 surface area to volume ratio
The passage of water from the less concentrated solution to the more concentrated solution across a partially permeable membrane is a process called osmosis
Diffusion is the movement of molecules from the area of higher concentration to the area of lower concentration i.e.along concentration gradient .
Osmosis is the movement of water across a semi-permeable member from a solution of lesser solute concentration to a solution of higher solute concentration .
Diffusion is the movement of atoms and molecules from a region of higher concentration to a region of lower concentration.An example of diffusion is;A drop of ink diffuses into the glass soon,the entire glass will be coloured . Osmosis is the net movement of water molecules through partially permeable membrane,from a place of higher water concentration to a place of lower water concentration.An example of osmosis is;water enters or leaves the plants through partially permeable membranes by osmosis.These two processes are known as passive transport processes.The difference between osmosis and diffusion is that,In diffusion,we do or do not need partially permeable membrane,while in osmosis,we always need partially permeable membrane.
osmosis is the movement of water through a semi-permeable membrane.
if you know what facilitated means then add what diffusion means
Osmosis is the diffusion of water through a semi-permeable membrane, such as that surrounding a cell. Semipermeable indicates that the membrane will allow certain thing to pass through it while preventing others.
Facilitated diffusion uses integrated proteins that act as channels for ions or molecules to pass through.
The processes that take material into cells are osmosis and diffusion. This is usually facilitated by the selective permeable membrane of the cell.
Osmosis is the diffusion of water.
osmosis is diffusion through a membrane
Facilitated Diffusion
facilitated diffusion
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.

diffusion and osmosis are types of ways to get materials into or out of a cell
osmosis is the movement of water across the plasma or cell membrane
