In facilitated diffusion, there are temporary openings in the cell membrane that enable certain molecules to pass through quickly.

What substance will diffuse through a membrane?
The three substances that can diffuse through a cell membrane are CO2, O2, AND H2O.
Which substance did not diffused through the membrane?
starch doesnt diffuse through the dialysis membrane.
What is a transport process by which gases move through a membrane?
Simple Diffusion
What is the difference of osmosis and diffusion?
Diffusion is the process by which a substance passes through a membrane passively.Osmosis IS diffusion, just the substance involved is water.
What type of substances pass through the membrane by facilitated diffusion?
soluble materials which can diffuse passively .
Osmosis is the diffusion of what substance through a cell membrane?
Water
How does osmosis and diffusion differ?
Osmosis is a type of diffusion but through a barrier (membrane) while "diffusion" is not specified if there is a physical barrier or not. Gases diffuse through each other readily.
What substance is most likely to passively diffuse across the plasma membrane by dissolving in the membrane?
Lipid-soluble molecules such as O2 and CO2 diffuse freely through the plasma membrane.
When is a substance most likely to diffuse into a cell?
If there is the concentration of substance inside the cell is lesser than outside and cell membrane is permeable to the substance.
What characteristics is more likely to make a substance diffuse through the cell membrane?
Size. Actually very few substances are able to diffuse across the menbrane, most must be transported ie facilitated diffusion, active transport, or receptor-mediated endocytosis. Carbon dioxide, oxygen, water, and some lipid substances are able to diffuse across the membrane
How are osmosis and diffusion different?
Diffusion is the net movement of a substance through a membrane from a higher concentration to a lower concentration. Osmosis is the diffusion of water.
Diffusion is the movement of a sustance?
Diffusion is the movement of particles in a substance through a semi permeable membrane. Osmosis is similar but only involves water particles passing through a semi permeable membrane.
