which statements accurately describe osmosis?
443199
The best statement that accurately describes osmosis is: Osmosis is the diffusion of water across a membrane.

Explanation: Osmosis involves water moving from an area of low solute concentration to an area of high solute concentration across a semi-permeable membrane. ... Put more simply, dialysis is the movement of molecules in solute (e.g. glucose) and osmosis is the movement of the solvent (water) itself.

The main difference between the two is that diffusion can occur in any mixture, even when two solutions aren't separated by a semipermeable membrane, whereas osmosis exclusively occurs across a semipermeable membrane. There are actually three types of passive transport processes.

This highlights a noticeable difference between osmosis and facilitated diffusion. Osmosis involves movement of water molecules across a semi permeable membrane. ... A major difference can be noted that osmosis requires water molecules but facilitated diffusion does not require any water molecules.

Osmosis is the movement of water molecules through the cell. Diffusion is the movement of molecules, such as oxygen, in and out of a cell. The process by which water molecules are able to diffuse through the cell membrane. The movement of small molecules from a higher concentration to an area of lower concentration.

Osmosis: In osmosis, water always moves from an area of higher water concentration to one of lower concentration. In the diagram shown, the solute cannot pass through the selectively permeable membrane, but the water can. ... In this example, the solute cannot diffuse through the membrane, but the water can.

Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.

Osmosis is a special case of diffusion in which the molecules are water and the concentration gradient occurs across a semipermeable membrane. ... Reverse osmosis occurs when the water is moved across the membrane against the concentration gradient, from lower concentration to higher concentration.

That's what osmosis is and that's what forward osmosis is. Reverse osmosis uses that same semi-permeable barrier or membrane, but instead of allowing fresh water or lower-saline water to move across to a higher concentration to dilute that side, you do the opposite. ... That's a major difference between RO and FO.

When thinking about osmosis, we are always comparing solute concentrations between two solutions, and some standard terminology is commonly used to describe these differences: Isotonic: The solutions being compared have equal concentration of solutes. Hypertonic: The solution with the higher concentration of solutes.

Diffusion is the movement of particles from a high to lower concentration. Osmosis is the diffusion of water across a membrane.

The motion of molecules is through the semi-permeable membrane in osmosis, whereas in diffusion motion is direct and does not require a semi-permeable membrane. Osmosis undertakes in liquid medium only, whereas the process of diffusion undertakes in any medium (solid, liquid and gases).

In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.

Transport in cells Diffusion is the movement of particles from a high to lower concentration. Osmosis is the diffusion of water across a membrane. Active transport moves particles from low to higher concentration.

The differences between osmosis and diffusion it that diffusion refers to the movement of any chemical from one place to another, whereas osmosis exclusively refers to the movement of water across a membrane. also diffusion is the movement of molecules (solute or particles).

Osmotic pressure is a colligative property. This means, that the property depends on the concentration of the solute, but not on its identity. Example: The osmotic pressure difference would be zero, if pure water were on both sides of the semi-permeable membrane.
