What make osmosis and diffusion the same?
Molecules travel across the cell membrane from a higher concentration to a lower concentration during both osmosis and diffusion. Diffusion is when molecules move across the cells' membrane from a higher concentration to a lower concentration. Osmosis is the diffusion of water.
Explain how osmosis differs from diffusion?
Osmosis differs from Diffusion because in osmosis only water moves, and during diffusion, small molecules move across the cell membrane.
What are the materials required for osmosis?
Osmosis occurs when there are two solutions of different concentration strength separated by a semipermeable membrane. The membrane must allow water to cross, but not the solutes. Water will then move from the solution of lower concentration strength across the membrane to the solution of higher concentration strength. This movement of water is called osmosis.
What molecules move across during osmosis?
The only molecules that move during osmosis are water (H2O) molecules.
Why is diffusion of water vapour not an example of osmosis?
Osmosis is the movement of water molecules but water must also be in the liquid state and move across a semi-permeable membrane. Water as water vapour acts like a gas so this cannot be called osmosis.
What uses a protein to move a molecule across a membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
When osmosis occurs specifically which molecule move across a semipermeable membrane?
Osmosis is defined as the passive movement of water molecules from a region of low solute concentration to a region of high solute concentration through a partially permeable membrane; water molecules are thus exhibiting the movement.
What type of molecule can be used as a tunnel to move compounds across the cell membrane?
Lipid molecule
What process does not require energy to move a substance across a membrane?
Osmosis because it is the equalization of pressure.
What two processes move large packets of molecules across the cell membrane?
osmosis and diffusion
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 is it when a molecule uses energy to move across a semipermeable membrane?
active transport

What is formed when enzymes move hydrogen ions across a membrane to an area of greater concentration?
I will say the answer is osmosis or diffusion...I'll go with osmosis. MC
