How does water move during osmosis?
osmotic pressure should produce a net movement of water into a typical cell that is surrounded by water
How does the addition of solutes affect water potential?
adding the solute raises the boiling point of the water.
What is the primary driving force for osmosis?
Osmosis is the movement of water through a semi-permeable membrane. When there are different concentrations on either side, the water moves from the side that has the least concentration of solute to the side with the higher concentration of solute. So a different solute concentration drives osmosis.
Whats the only substance that carries out osmosis?
The only substance that carries out osmosis is water. Osmosis is the movement of water through a semi-permeable membrane from a low concentration of solute to a high concentration of solute in the pursuit of equilibrium across the membrane.
How does osmosis occur?
Osmosis is the movement of water from an area of high water potential to an area of low water potential across a semi-permiable membrane.
What is the osmosis definition?
"Osmosis is the diffusion of a solvent (frequently water) through a semi-permeable membrane, from a solution of low solute concentration (high water potential) to a solution with high solute concentration (low water potential), up a solute concentration gradient."
What is osmosis and its application?
http://www.answers.com/topic/osmosis The applications listed on that website are very informative, but the description of osmosis is lacking a few details. It would be a good idea to supplement your reading of that web page with this information:It is a common misconception that osmosis is the diffusion of water in only one direction. In reality, water molecules will diffuse in both directions during osmosis, but the rate of diffusion from a region of high water potential (low solute concentration) to a region of low water potential (high solute concentration) will be higher than the rate of diffusion back into the region of high water potential/low solute concentration. Thus osmosis is the net movement of water across a semi-permeable membrane, from a region of high (more positive) water potential to a region of low (more negative) water potential. The word 'net' is very important in this definition, as it illustrates that we are referring to the overall effect, rather than individual molecular movements.It is also important to remember that osmosis does not stop when "there is an equal solute concentration on both sides of the membrane". Osmosis will 'stop' when the water potential on either side of the membrane is equal, which may occur when one side still has a higher solute concentration, since other factors also effect osmosis (eg pressure). Even when osmosis 'stops', water will still diffuse in both directions, but at equal rates (the system has reached equilibrium).
How does water move during osmosis?
osmotic pressure should produce a net movement of water into a typical cell that is surrounded by water
Why does the addition of a solute with polar molecules to one side of a membrane result in diffusion of water?
Addition of a polar solute lowers the water potential on that side of the membrane and so water will diffuse from the other side of the membrane from a relatively high water potential to the lower water potential, by osmosis.
What is the process of water moving from a low solute concentration to a high solute concentration?
hypertonic
How does water leave a cell when placed in salt water?
osmosis, which is diffusion of water across a membrane from an area with lower solute concentration to an area of higher solute concentration to equalize the concentration on both sides of the membrane.
The movement of the water across a membrane is termed?
The term used is osmosis. the direction of movement across the membrane is dependent on the concentration of solutes (known as the solute potential) which directly effects the osmotic potential.
What is the process in which water diffuses through a selectively permeable membrane is called?
Osmosis is the net movement of water across a partially permeable membrane from a region of high solvent potential to an area of low solvent potential, up a solute concentration gradient.
What is osmosis?
osmosis is a movement of a fluid that passes through a semipermable membrane
What is the process of water moving from an area of low solute concentration to an area of high solute concentration?
Osmosis is the process of water moving from an area of low solute concentration to an area of high solute concentration.
What is the process of water moving from an area of low salute concentration to an area of high solute concentration?
Water does flow to a region of more concentrated solute, by the process of osmosis.
What is the diffusion of water into and out of a membrane?
This is called osmosis, which is the movement of water from a low solute concentration to a high solute concentration.
