osmosis is the diffusion of water. In diffusion, substances move from an area of high concentration to and area of lower concentration, or from a hypotonic solution to a hypertonic solution. Free water concentration just refers to the concentration of solute in a solution (in osmosis, water). If the concentration of solute is higher outside of a cell bits of solute will move towards the area of lower concentration: inside the cell. If the concentration of solute is higher within the cell then some solute will leave the cell. Cells "want" to be isotonic, or to have equal amounts of solute both inside and out. When a cell reaches an isotonic state it wants to stay that way, so the water moves across the membrane at the same rate.
Hope that helps!

What else can I help you with?
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.
Define the term osmosis?
Osmosis is the movement of water molecules across a semi-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.
What process is the diffusion of water through a selectively permeable membrane?
The process of water passing through a selectively permeable membrane is called osmosis. Water will move from an area of higher concentration to an area of lower concentration in order to equalize the solute concentrations on both sides of the membrane.
What is the name of the diffusion of water?
Osmosis. Osmosis is not the same as diffusion of water. Diffusion of water is just diffusion like with any other substance: the particles spreading, making a homogeneous distribution. Osmosis involves a semipermeabel membrane, where water goes from low solvent concentration to high solvent concentration.
When will the net osmosis rate equal zero in a model cell?
The net osmosis rate will equal zero when the concentration of solutes inside the cell is the same as the concentration of solutes in the surrounding solution. At this point, there will be no concentration gradient driving osmosis in either direction, resulting in no net movement of water across the cell membrane.
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.
What is the source of energy for osmosis?
The source of energy for osmosis is the potential energy stored in the concentration gradient of the solute particles across a semipermeable membrane. This concentration gradient creates a driving force that leads to the movement of water molecules from an area of low solute concentration to an area of high solute concentration, resulting in osmotic flow.
The net movement of water across a membrane from the solution of lower concentration to one of higher concentration is called?
This is referred to as OSMOSIS. When you say "solution of lower concentration" this implies the solute concentration is low, thus water concentration is high. So, osmosis is movement of water from a high concentration of water, to a lower concentration of water, just to be clear.
Do osmosis has a high or low concentration?
As per Definition of osmosis: "Osmosis is the passage of water from the region of high water concentration through a semi permeable membrane to a region of low water concentration". Thus, Osmosis do have an area of high and low concentration of water solutions.
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.
5 differences between diffusion and osmosis?
The differences between diffusion and osmosis are really just that osmosis takes place with water and through a membrane. Diffusion is just the spread of molecules from high concentration to low. Osmosis is diffusion of water through a membrane.
Why does the concentration gradient affect osmosis?
Osmosis is the movement of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration. The concentration gradient, or difference in solute concentration between two solutions, affects osmosis because water moves to areas with higher solute concentration to equalize concentrations on both sides of the membrane.
What is osmosis and reverse osmosis?
Osmosis is the movement of water molecules from a region of high concentration to a region of low concentration through a semi-permeable membrane. Reverse osmosis is a process where external pressure is applied to force water molecules through a semi-permeable membrane, leaving impurities behind. It is commonly used for producing clean drinking water.
How does water typically move in osmosis?
In Osmosis, water moves from the region of high water concentration through a semi permeable membrane to a region of low water concentration. Osmosis happens because of diffence in concentration of water different regions.
What direction does osmosis go on the concentration gradient?
Osmosis occurs from an area of higher water concentration to an area of lower water concentration, moving down the concentration gradient.
The movement of water molecules across selectively premeable?
Osmosis movement of water from high concentration to low concentration.
Define the term osmosis?
Osmosis is the movement of water molecules across a semi-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.
