Diffusion is a process that occurs naturally everywhere. All molecules and particles that are in an area of higher concentration in a gas or liquid will tend to move to an area of lower concentration. That is diffusion.
the cell membrane
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
For diffusion to occur there needs to be a concentration gradient. Which means that the concentrations on the two sides must be different. In diffusion the particles flow from high concentration to low concentration.
Diffusion will most likely to occur where there is a high concentration of gas or water then the particles distibute evenly to the area of low concentration. for example if you could smell a turkey cooking in the oven from upstairs without anyone telling you.
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
Diffusion occurs on the cell membrane.

diffusion
Diffusion is a form of passive transport, so nothing is required for it to occur.
The cell will work but not very well because osmosis and diffusion did not occur but sometimes it will work anyways
the process that causes the water to enter and leave the cell is diffusion
For diffusion to occur there needs to be a concentration gradient. Which means that the concentrations on the two sides must be different. In diffusion the particles flow from high concentration to low concentration.
diffusion is occur when different concentration gradient is applied
yes, it can occur in various ways. (active transport, simple diffusion,etc.)
Diffusion will most likely to occur where there is a high concentration of gas or water then the particles distibute evenly to the area of low concentration. for example if you could smell a turkey cooking in the oven from upstairs without anyone telling you.
