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.
When water moves through an area of higher concentration to lower concentration?
This movement is called osmosis. It is a natural process where water molecules pass through a semipermeable membrane from an area of higher water concentration to an area of lower water concentration. Osmosis helps maintain equilibrium in cells by regulating the flow of water and nutrients.
What substances move into and out of cells by diffusion?
Substances that move into and out of cells by diffusion include oxygen, carbon dioxide, and small non-polar molecules like water and lipid-soluble molecules. Diffusion is a passive process where molecules move from an area of higher concentration to an area of lower concentration to reach equilibrium. This process does not require energy input from the cell and is essential for maintaining cellular homeostasis.
What does water chases osmoles mean?
This statement means that as the solute concentration increases, the concentration of water decreases. Osmosis is the diffusion of a solvent such as water. Osmosis occurs whenever there is a difference of water concentrations between two sides of a membrane. The water diffuses to the side of the membrane which contains the highest concentration of solutes. by Together.
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.
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 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.

What is the difference between diffusion and bulk flow in terms of the movement of substances across a membrane?
Diffusion is the movement of substances from an area of high concentration to low concentration, while bulk flow is the movement of substances in a fluid due to pressure differences. Diffusion occurs passively, while bulk flow requires energy.
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.
What does the net flow of water molecules in osmosis depend on?
The net flow of water molecules in osmosis depends on the concentration of solute particles on either side of the membrane. Water will move from an area of low solute concentration to high solute concentration in an attempt to reach equilibrium.

When there are different amounts of a 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.
