Osmosis is the tendency of water to flow from high concentration to low concentration. Osmosis, gravity, pressure, and matrix effects (cohesion, surface tension, etc.) all factor into the final water potential.

What is it called when water diffuses across a cell membrane?
Passive molecular diffusion. The Cell can't be compared to a hollowed out potato! Meaning that the osmotic flow of water into the sugar filled potato interior pool is unidirectional; while the Cell may control the flow of water, in or out, depending upon it's needs.
What is the a major difference between facilitated diffusion and active transport?
Simple diffusion moves molecules from an area of higher concentration to an area of lower concentration without an input of energy. Facilitated diffusion follows the same rules as regular diffusion (higher to lower concentration and no energy input), but uses protein carrier molecules to allow substances that are fat soluble to diffuse through the cell membrane.
What substances move into and out of cells by diffusion?
diffusion- substances move across the cell membrane from areas of high concentration to areas of low concentration osmosis is the diffusion of water across a cell membrane (area of high concentration to an area of low concentration)
What is the diffusion that controls the flow of water in and out of a cell?
The process of "diffusion" of water is called "osmosis". Water moves from an area of high concentration to low concentration. So, for example, if you put a cell in a hypotonic solution (ie where there is a lower concentration of salts etc outside the cell, and thus more water) then the water will flow into the cell to balance out the salt concentrations. In this case the cell will swell (and could even explode). If you put the cell in a hypertonic solution, then the concentration of salts outside the cell is higher than inside and so water flows from the cell out into the environment causing the cell to shrivel. If you put a cell in an isotonic environment (the salt concentration is the same on both sides of the cell membrane) then the flow of water in and out of the cell is equal so the cell does not shrink or swell.
How is the concentration gradient of a substance important to diffusion?
In diffusion, substances flow with a concentration gradient, meaning that they flow from areas of high concentration to areas of lower concentration. Flowing against a concentration gradient would be going from an area of low concentration to an area of higher concentration, but this only occurs in active transport.
How do diffusion and osmosis differ from one another?
Diffusion and osmosis differ because diffusion is the process by which molecules spread out, or move from areas with high concentration to low concentration, and osmosis is the diffusion of water. Osmosis is a type of diffusion relating to water. It is usually used to describe the diffusion of water across a membrane (such as the cell membrane). Osmosis is also defined as the flow of solvent from a region of higher pressure toward a region of low pressure.
What regulates the flow of water through a cell membranes?
concentration of water A concentration of solutes regulates the flow of water through a cell membrane.
What does the direction of H plus diffusion across a membrane depend on?
Concentration. It will generally flow from an area of high concentration to an area of low concentration.
The difference between diffusion and osmosis?
Diffusion is when molecules travel from a higher concentration to a lower concentration. For example when you have air freshener on one side of the room it will spread to the other because the scent molecules are diffusing through the air. Osmosis is the movement of water molecules from higher concentration to a lower concentration.
What transport mechanisms involves the movement of water in a cell?
The membrane of a cell is semipermeable. Water and small molecules flow freely into and out of the cell. There is no transport mechanism. The fluidity of the membrane designated by the fluid mosaic model, allows for water to flow freely into and out of the cell.
When there are different amounts of substance on either side of the cell membrane a what gradient results?
It is known as a concentration gradient which in diffusion will always flow from areas of high concentration to areas of lower concentrations.

How do nutrients flow through the membranes?
Mostly because of a difference in concentration between the intra- and extracellular space. Because of this, diffusion through a membrane occurs.

For diffusion to occur there must be?
For diffusion to occur there needs to be a concentration gradient. Which means that the concentrations on the two sides must be different. In diffusion the particles flow from high concentration to low concentration.
