The conditions necessary for diffusion is firstly a semi permeable membrane, and a concentration gradient for the movement of molecules from higher concentration to lower concentration. The size of the molecules should be small enough to pass easily through the membrane.

∙ 13y agoGlucose, sodium ions and chloride ions are some examples of molecules and ions that must efficiently get across the plasma membrane, however the lipid bi layer of the membrane is virtually impermeable to them. Their transport must therefore be facilitated by proteins that span the membrane and provide an alternative route or bypass.
Facilitated diffusion involves protein carriers, which can transport substances in either direction across the membrane.
Facilitated diffusion is passive, and therefore requires no energy input. However, there must be a concentration gradient.

Diffusion can take place if the two substances are?
Diffusion can take place in any substance, cause diffusion means the mixture of gases . In a perfume shop diffusion takes place
A form of passive transport that uses transport proteins-?
Diffusion (passive transport) needs no energy to take place, and therefore no need for transport or carrier protiens. Active transport uses carrier protiens, as the cell needs to work against a concentration gradient. This requires energy. Diffusion can take place outside of cells Active transport can't take place outside of cells.
How does diffusion take place?
Molecules move from an area from where there is a high concentration to an area where there is a low concentration. This occurs until equilibrium is reach. After equilibrium is reached, diffusion still occurs. (but in "equal trade") Diffusion is caused by the random movements of molecules.
What happens in the process of facilitated diffusion In what part of the membrane does it take place?
In facilitated diffusion, substances will still diffuse down their concentration gradient but they make use of a transport protein.
