What else can I help you with?
When water diffuses through a selectively permeable membrane?
Diffusion without a concentration gradient; osmosis with.
What is the process in which water diffuses through a selectively permeable membrane is called?
The process in which water diffuses through a selectively permeable membrane is called osmosis. Osmosis occurs when water molecules move from an area of higher water concentration to an area of lower water concentration to balance out solute concentrations on either side of the membrane.
What is is required for diffusion to occur?
A concentration gradient and a (semi-)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.
What determines the direction in a substance diffuses across a membrane?
The concentration gradient determines the direction in which a substance diffuses across a membrane. The concentration gradient is a measure of how the concentration of a substance changes from one place to another.

What is the process in which water diffuses through a selectively permeable membrane is called?
The process in which water diffuses through a selectively permeable membrane is called osmosis. Osmosis occurs when water molecules move from an area of higher water concentration to an area of lower water concentration to balance out solute concentrations on either side of the membrane.
Osmosis always involves what?
Osmosis refers to the flow of water along the water potential through a selectively/differentially permeable membrane/tubing due to a difference in water potential. Thus, it always involves 1) a selectively/differentially permeable membrane 2) difference in water potential(related to concentration gradient) 3)flow of water.
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 is the scientific definition of osmosis?
Osmosis is the movement of water molecules across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration, in order to equalize the concentration of solute on both sides of the membrane.
Does osmosis use cell energy?
No, osmosis is a passive process that does not require the use of cell energy (ATP). It is driven by the concentration gradient of solutes across a selectively permeable membrane.
Does osmosis need oxygen?
Osmosis refers to the flow of water along the water potential through a selectively/differentially permeable membrane/tubing due to a difference in water potential. Thus, it does not require oxygen.
Does osmosis go with the concentration gradient?
Yes, osmosis involves the movement of water molecules across a selectively permeable membrane from an area of high water concentration to an area of low water concentration. This movement occurs in response to the concentration gradient of water molecules.
What does it mean if a cell is selectively permeable?
In Biology, a selective permeable cell means the cell only allows certain molecules to pass through. This concept was first introduced to understand the process of osmosis, where solute molecules move along a concentration gradient through a semi permeable membrane (also known as a selectively permeable membrane) Cells allow water molecules and small ions to pass through their membranes without the expenditure of energy.
What is osmososis?
Osmosis is the movement of water molecules from an area of low solute concentration to an area of high solute concentration through a semi-permeable membrane. This process helps maintain balance in the concentration of solutes inside and outside of cells.
What can be considered as passive transport?
Any form of transport that does not require a form of energy, which means that it happens along a concentration gradient (from an area of high to low concentration) and across a selectively permeable membrane (Osmosis)
What is the term for the Diffusion of water across the concentration gradient?
The term for the diffusion of water across a concentration gradient is osmosis. Osmosis refers to the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
