What is the movement of molecules from an area of high concentration to an area of low concentration called?

Diffusion

When molecules move down their concentration gradient they move from where they are more concentrated to where they are?

A concentration gradient occurs when the concentration of particles is higher in one area than another. In passive transport, particles will diffuse down a concentration gradient, from areas of higher concentration to areas of lower concentration, until they are evenly spaced.

Which term refers to the movement of molecules from an area of higher concentration?

Diffusion is the process by which particles move from an area of high concentration to an area of lower concentration.

When the concentration of a material is the same inside and outside?

10th grade Biology – 7-3 Cell Boundaries

A B
the diffusion of water through selectively permeable membrane osmosis
the concentration of solutes is the same inside and outside the cell isotonic
solution has a higher solute concentration than the cell hypertonic
solution has a lower solute concentration than the cell hypotonic

Which side of the membrane has a more concentrated sugar solution?

The solution outside the cell is more concentrated. The ratio of solute outside the cell is higher than inside the cell. In which direction are water molecules moving, into or out of the cell?

Which solution is more concentrated with water on Side A in Model 1 the solution inside the cell or the outside?

Water molecules are small enough to pass through. What is the ratio of water to sugar inside and outside the cell? Which solution in Model 1 is more concentrated-the solution inside or outside the cell? The solution outside the cell is more concentrated.

Is there more water in a concentrated solution?

Model 2 shows a cell bounded by a selectively permeable membrane. There is a sugar solution inside the cell and outside the cell. In a concentrated solution there is more/less water.

Why osmosis is a special kind of diffusion?

Osmosis is a special kind of diffusion because in both cases there is a movement of particles from a higher concentration region to a lower concentration region. The only difference is that osmosis is applicable to the movement of the solvent only through the semi-permeable membrane where the solvent is water.

Is Osmosis a special form of diffusion?

You can consider osmosis to be a special case of diffusion in which diffusion occurs across a semipermeable membrane and only the water or other solvent moves. Diffusion and osmosis are both passive transport processes that act to equalize the concentration of a solution.
