what is the correct description of the relationship between osmosis and diffusion?
476187
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.

Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient." The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, movement of molecules does not stop.

Diffusion sees molecules in an area of high concentration move to areas with a lower concentration, while osmosis refers to the process by which water, or other solvents, moves through a semipermeable membrane, leaving other bits of matter in its wake.

Diffusion occurs with or without a membrane between two areas of different concentrations of molecules. However, osmosis only occurs across a semipermeable membrane, a membrane that prevents many particles or molecules to freely travel between the two sides, while allowing water to pass through.

Simple diffusion is the process by which solutes are moved along a concentration gradient in a solution or across a semipermeable membrane. ... If the molecules are small enough, this simple diffusion can happen across cell membranes, between the individual phospholipids that make up the membrane.

No energy is required to go from a high concentration to a lower one. Osmosis is, quite simply, diffusion by water. ... This is against the natural tendency of moving from high to low, therefore it requires the cell to expend energy, stored in the form of ATP.

"In osmosis, water moves from areas of low concentration of solute to areas of high concentration of solute." ... So osmosis only occurs with a semipermeable membrane, and even with the membrane some water will move both sides.

Explanation: osmosis is the process in which water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane, so little energy is required to carry out this process, thus it is a form or passive transport.

Osmosis can only function in a liquid medium, but diffusion can occur in all three mediums (solid, liquid and gas). Furthermore, osmosis requires a semi-permeable membrane while diffusion does not. The intake of water in plants is an example of osmosis.

When people discuss osmosis in biology, it always refers to the movement of water. ... One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but when we talk about osmosis, only the solvent molecules (water molecules) cross the membrane.

Osmosis is the diffusion (i.e. movement) of a solvent (e.g. water) across a semi-permeable membrane. Dialysis is the separation (i.e. movement) of molecules themselves.

the cell membrane is freely permeable to water. ... Osmosis is the diffusion of the water molecules across a membrane. 2. Osmosis occurs across a selecvively permeable membrane that is freely permeable to water but not freely permeable to solutes.

Simple diffusion and osmosis are in some ways similar. Simple diffusion is the passive movement of solute from a high concentration to a lower concentration until the concentration of the solute is uniform throughout and reaches equilibrium.

So osmosis only occurs with a semipermeable membrane, and even with the membrane some water will move both sides.

Osmosis is the process by which water molecules move from a weaker solution into a stronger solution through a partially permeable membrane. ... Transpiration is the loss of water in vapour form from the leaves into air. It occurs when water is released into air.

Osmosis is the process of diffusion of a fluid through a semi-permeable membrane (intestines are a biological example). Osmotic pressure is the pressure used to force soluble materials out of a fluid, or the pressure build up from the fluid movement once past the membrane.

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.
