Osmosis is the diffusion of water across a selectively permeable membrane in which water moves from a solution containing a low concentration of solute to what kind of solution?
a solution containing a high concentration of solute
How is diffusion different from osmosis?
The essential idea is the same: diffusion is the process by which molecules spread from areas of high concentratiion, to areas of low concentration. Osmosis is the process by which molecules of WATER spread from areas of high concentration (such as a dilute solution) to areas of low concentration (such as a concentrated solution), typically through a selectively permeable membrane. In short: Diffusion occurs as is, while osmosis occurs through a semi permeable membrane.
What is diffusion and osmosis?
Diffusion is the tendency of particles in a gas or liquid to become evenly distributed by moving from areas of greater concentration to areas of lesser concentration. Diffusion is driven by the kinetic energy of particles that is a consequence of temperature. It is an inherently random process and particles continue to spread out until they are evenly distributed within the enclosed area.Biologically, diffusion is the cause of random movement or net movement of particles from an area of high concentration towards an area of low concentration. Osmosis refers to the flow of particles across a membrane. When active transport is absent, diffusion provides the driving force for osmosis across a fully permeable or partially permeable membrane.Fully permeable: all particles can move through.Partially permeable: only certain particles an move through.Active transport: biochemical processes expend energy to move particles.Note: Reverse osmosis is basically filtering. Pressure is greater on one side of a partially permeable membrane pushing particles through it.
How is osmosis different than diffusion?
Osmosis is the same thing as diffusion, but occuring only with liquids in a selectively permeable membrane. An example of this is that water entering your cells is osmosis, but oxygen entering is diffusion.
What is the relattionship between osmosis and diffusion?
Diffusion describes the movement of molecules from where they are abundant to where they are scarce - or from a region of higher concentration to a region of lower concentration Osmosis is diffusion through a semi-permeable membrane
Osmosis is the diffusion of water across a selectively permeable membrane in which water moves from a solution containing a low concentration of solute to what kind of solution?
a solution containing a high concentration of solute
When water diffuses through a selectively permeable membrane?
Diffusion without a concentration gradient; osmosis with.
What is the movement of water through a selectively permeable membrane?
The movement of water through a selectively permeable membrane is called diffusion. Water will always diffuse down a concentration gradient, from high solute concentration to low solute concentration.
What process - movement of water across a selectively permeable membrane from an area of high water concentration to an area of low concentration?
Osmosis is the process by which water moves across a selectively permeable membrane.
What materials does osmosis transport?
Osmosis is the diffusion of water across a selectively permeable membrane from where it(water) is in higher concentration to where it(water) is in lower concentration.
What is the diffusion of water across the selectively permeable?
osmosis
How does oxygen cross a selectively permeable membrane?
diffusion
How the terms in each pair differ in meaning of osmosis and diffusion?
Osmosis is the diffusion of water through a selectively permeable membrane. Diffusion refers to the simple property of moving from an area of high concentration to an area of low concentration so that the concentration of the total area will be equal and balanced (at equilibrium). Diffusion can occur with any substance and does not require but can involve a permeable membrane.
Which term refers to the diffusion of water molecules through a slestively permaeable membrane?
The movement of water through a selectively permeable membrane is called diffusion. Water will always diffuse down a concentration gradient, from high solute concentration to low solute concentration.
When molecules move from high concentration to low concentration this is called?
diffusion unless it is water molecules moving through a selectively permeable membrane in which case it is osmosis
Is it true if the process by which water moves across a selectively permeable membrane is called diffusion?
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
Diffusion of water molecules across a selectively permeable membrane?
it is osmosis
