What is it called when a molecule moves across a semipermeable membrane?
Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution.
What is the diffusion of water through a selectively permeable membrane called quizlet?
The diffusion of water across a selectively permeable membrane is called osmosis.
What is diffusion across a semipermeable membrane quizlet?
STUDY. Diffusion. – Diffusion is the net movement of a solute from an area of higher concentration to an area of lower concentration. – Diffusion is the result of the random movement of molecules.
Which process moves water molecules across the membrane of a cell quizlet?
what is osmosis? Osmosis is the diffusion of water molecules through the selectively permeable membrane.
What is the diffusion of water down its own concentration gradient through a selectively permeable membrane called quizlet?
Osmosis: The diffusion if water across a selectively permeable membrane. The direction of water movement based on differences on solute concentrations depends on how the water diffuses down its own concentration.
What is the movement of osmosis?
Osmosis is the movement of water through a semipermeable membrane according to the concentration gradient of water across the membrane, which is inversely proportional to the concentration of solutes.
What is a semipermeable membrane quizlet?
-A semipermeable membrane, also termed a selectively permeable membrane, a partially permeable membrane or a differentially permeable membrane, is a membrane that will allow certain molecules or ions to pass through it by diffusion and occasionally specialized “facilitated diffusion.
What is solution diffusion?
“Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.”
What is difference between osmosis and reverse osmosis?
In natural osmosis, the freshwater will cross the semipermeable membrane and dilutes the concentrated solution. In reverse osmosis, the pressure is applied towards the concentrated aqueous solution and the water molecules are forced to cross the membrane towards the freshwater.
What is the process of water moving across a semipermeable membrane quizlet?
Osmosis is the diffusion of water molecules through a selectively permeable membrane.
In what direction do water molecules move through a semipermeable membrane quizlet?
It always goes from higher to lower concontration, and because the cell membrane is semi-permeable, the water is always allowed to pass through.
What is the diffusion of water down its concentration gradient through a selectively permeable membrane called?
Osmosis
Osmosis is the net movement of water across a selectively permeable membrane driven by a difference in solute concentrations on the two sides of the membrane. A selectively permiable membrane is one that allows unrestricted passage of water, but not solute molecules or ions.
What is another word for osmosis?
In this page you can discover 7 synonyms, antonyms, idiomatic expressions, and related words for osmosis, like: ultrafiltration, diffusion, absorption, filtration, passage, flocculation and assimilation.
What is diffusion osmosis and filtration?
The processes of diffusion, osmosis, and filtration are responsible for the movement of materials into and out of body cells as well as the exchange of molecules between body fluid compartments. These processes involve some basic principles of physics which will be demonstrated in this laboratory.
