A change in concentration of solutes on either side of the membrane. Depending on the tonicity of the inner-membrane and the outside of the membrane, plasmolysis or cytolysis may occur.

When does diffusion occur across a cell membrane?
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
What does diffusion do in a cell?
Move things across the cell membrane.
What the diffusion of water across a cell's membrane?
The diffusion of water through a cell membrane is called osmosis.
Is diffusion of molecules across the cell membrane the most complex type of active?
No, diffusion of molecules across a cell membrane is a passive process, not active, and arguably the least complex.
Is a special type of diffusion that involves moving across a cell membrane?
osmosis is a special type of diffusion that involves water moving across a cell membrane hopefuly this helped :)
What are the processes involved in moving substances across the cell membrane?
Diffusion
What is the proccess by which water moves across a cell's membrane?
Passive diffusion.
What hormone aids the diffusion of glucose across the cell membrane?
INSULIN
What used a protein to move a molecule across a cell membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
What doesn't occur as a cell grows larger in size?
Diffusion across the cell membrane is impaired
What is the movement of across the cell membrane using cell energy?
This type of movement is called simple diffusion.
What cause certain things to enter cell?
Things can enter the cell through various processes, such as osmosis, diffusion and active transport. Passive transport (diffusion/osmosis) occurs because of a difference in concentration across the membrane.
