what describes the difference between osmosis and diffusion?

Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. ... Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.

What is the difference between osmosis and diffusion? 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 movement of materials through the cell membrane need to use the cell's supply of own energy.

Direct link to Isabella Nicolè's post “"In osmosis, water moves from areas of low concent...” "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.

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.

Mass flow is the movement of dissolved nutrients into a plant as the plant absorbs water for transpiration. ... Diffusion is the movement of nutrients to the root surface in response to a concentration gradient.

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.

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.

Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. ... Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration.

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.

How are gradients important in diffusion and osmosis? It is what makes diffusion and osmosis happen. Without gradient, there would be no need for movement from high to low concentrations. If all cell were isotonic, there would be no flow of nutrients.

Facilitated diffusion is the movement of a molecule from an area of high concentration to an area of lower concentration with the help of a protein channel or carrier. ... Osmosis is the diffusion of water through a semi-permeable membrane.

Diffusion is the movement of one specific molecule from a high concentration area to a low concentration one. Filtration is the movement of a fluid (mixture of several molecules) from a region of high pressure to a region of a low pressure.

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

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 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.

Osmosis is a specific type of diffusion; it is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration.

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.
