Osmosis occurs across a membrane due to the movement of solvent molecules (usually water) from an area of lower solute concentration to an area of higher solute concentration to equalize the concentration on both sides of the membrane. This process is driven by the tendency of solutes to diffuse and reach equilibrium.

What process do water molecules cross the cell membrane?
Water molecules cross the cell membrane through a process called osmosis, which is driven by the concentration gradient of water inside and outside the cell. Aquaporin proteins on the cell membrane facilitate the movement of water molecules into and out of the cell.
What process is the diffusion of water through a selectively permeable membrane?
The process of water passing through a selectively permeable membrane is called osmosis. Water will move from an area of higher concentration to an area of lower concentration in order to equalize the solute concentrations on both sides of the membrane.
What process requires membrane proteins but not energy?
Facilitated diffusion is a process that relies on membrane proteins to transport molecules across the cell membrane without the need for energy input. These proteins act as channels or carriers to facilitate the movement of molecules from an area of high concentration to an area of low concentration.
Osmosis can only occur if water travels through the what?
Osmosis can only occur if water travels through the semi-permeable membrane. This will cause water to cross the lipid bilayer.
When water moves across a cell membrane it is called?
osmosis
Which type of molecules cross the membrane in osmosis?
Water molecules cross the membrane during osmosis. Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
What is the process where in the diffusion of water cross a cell membrane?
Osmosis
What process do water molecules cross the cell membrane?
Water molecules cross the cell membrane through a process called osmosis, which is driven by the concentration gradient of water inside and outside the cell. Aquaporin proteins on the cell membrane facilitate the movement of water molecules into and out of the cell.
What substances will cross the cell membrane through osmosis?
Only water is transported through the process of osmosis.
What structure allow small particles to cross cell membrane?
Osmosis.
Are the salt particles able to cross the membrane?
If you are referring to osmosis, the salt doesn't cross the membrane, water does. Water will move into the salt water to attempt to dilute it to create homeostatsis, or equal concentrations on each side of the 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 the diffusion of water across a cell's membrane?
The diffusion of water through a cell membrane is called osmosis.
Is movement of alcohol through cell membrane osmosis?
Alcohol moves across the cell membrane by means of osmosis.
