A concentration gradient and a (semi-)permeable membrane.
Energy is not required for passive transport to occur. Passive transport processes such as diffusion and osmosis rely on the inherent kinetic energy of molecules to move from an area of high concentration to an area of low concentration without the need for external energy input.
Yes, that's correct. A more soluble and diffusible gas can move more easily across a membrane due to its increased ability to dissolve and diffuse through the barrier, reducing the pressure gradient needed for diffusion to occur.
No, plasma is evil.
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.
Yes, it can.
Diffusion is a form of passive transport, so nothing is required for it to occur.
diffusion is occur when different concentration gradient is applied
Diffusion occurs on the cell membrane.
1 diff. Semi permiable membrane is required in osmosis while it is not required in diffusion. 2 diff. Osmosis cn occur only in liquid medium while diffusion cn occur in all mediums.
Diffusion is quicker at high temperatures and pressures.
Diffusion occur in all phases.
Diffusion occurs when something something something
a gradient
Yes.
Cells don't need to use any ENEGRY for diffusion particles to occur/happen
two molecules must collied before diffusion happens.
