Diffusion is the net movement of molecules from the region of higher concentration to region of lower concentration.
Explanation:
Diffusion is a passive process. It is like when you open a bottle of perfume, soon the whole room will be covered with its smell. From region where the concentration is high, the molecules move to the regions where the concentration is low down the concentration gradient unless equilibrium is reached. Diffusion is the net movement of molecules from the region of higher concentration to region of lower concentration.
it would depend on the concentration gradient. diffusion occurs along the c.gradient e.g if there is a higher concentration of molecules outside the cell and low concentration of molecules in cell then molecules will diffuse into the cell and vice versa.
Diffusion occurs in a direction from higher concentration towards lower concentration.
Random motions cause particles to move in and out of cells in any direction.
Diffusion occurs in one direction because it follows the concentration gradient from high to low. If the solution is isotonic, then the rate will be the same on both directions.
Molecules or particles with different sizes
From areas of high concentration to areas of low concentration.
low to high concentration
Down a concentration gradient
no energy
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.
No, plasma is evil.
yes
Yes, it can.
diffusion is occur when different concentration gradient is applied
Diffusion occurs on the cell membrane.
Diffusion is one of the processes of transferring materials within the cells of living organisms. An example of diffusion is the exchange of gases in the lungs.
Diffusion is quicker at high temperatures and pressures.
no energy
Diffusion occur in all phases.
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.
a gradient
Yes.
Diffusion occurs when something something something
There has to be a difference in concentration in order for diffusion and osmosis to occur.
Cells don't need to use any ENEGRY for diffusion particles to occur/happen
