What the diffusion of water across a cell's membrane?
The diffusion of water through a cell membrane is called osmosis.
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 part of an animal cell allows diffusion and osmsis occur?
the cell membrane
What hormone aids the diffusion of glucose across the cell membrane?
INSULIN
Why the line-with-gaps model is not suitable to explain facilitated diffusion?
Facilitated diffusion is a carrier-mediated form of transport across a membrane. The line-with-gaps model doesn't show the carrier proteins that are in the cell membrane. These proteins are what help facilitated diffusion occur.
What doesn't occur as a cell grows larger in size?
Diffusion across the cell membrane is impaired
Where diffusion occur?
Diffusion occurs on the cell membrane.
What does diffusion do in a cell?
Move things across the cell membrane.
When reffering to molecular transport does movement occur across the cell membrane?
yes, it can occur in various ways. (active transport, simple diffusion,etc.)
What does diffusion across the cell membrane cause?
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.

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.
What part of an animal cell allows diffusion and osmsis occur?
the cell membrane
What hormone aids the diffusion of glucose across the cell membrane?
INSULIN
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.
