Will a semipermable membrane allow only water through and not any sugar disovled in water?
Yes, that is correct.
Osmosis is the diffusion of water through a membrane but most of what is called osmosis in cells is actually due to a what related proccess?
Diffusion and Convection. In molecular diffusion, the moving entities are small molecules. Diffusion is the thermal motion molecules at heated temperature. Diffusion rate is a function of only temperature, and is not affected by concentration. I do believe this answer is most likely wrong.
How are diffusion and facilitated diffusion diffrent?
Diffusion directly passes through the cell membrane unaffected by the hydrophobic part of the membrane. Facilitated diffusion uses proteins to assist in the movement of molecules. Ions have trouble moving through the hydrophobic part of the membrane.
Does osmosis or facilitated diffusion require the presence of membrane channels?
facilitated diffusion
What the diffusion of water across a cell's membrane?
The diffusion of water through a cell membrane is called osmosis.
Does oxygen diffuse through a semipermable membrane?
yes
What is a osmosis?
osmosis is a movement of a fluid that passes through a semipermable membrane
What is called when a molecule moves across a semipermable membrane into a region of a higher concentration?
When a molecule moves to a higher concentration it needs help of a pump. We call this facilitated diffusion. Osmosis only deals with the movement of water.

Yes, that is correct.
What is osmosis?
osmosis is a movement of a fluid that passes through a semipermable 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.)
Facilitated diffusion required what?
Facilitated diffusion requires membrane proteins
When was Molecular Membrane Biology created?
Molecular Membrane Biology was created in 1978.
Where diffusion occur?
Diffusion occurs on the cell membrane.

What drives diffusion?
Diffusion is the movement of ions and other micro molecules across a barrier or membrane. Diffusion is caused by gradients on either side of the membrane.
Diffusion requires what?
Facilitated diffusion requires membrane proteins
