That's a definition of diffusion.
No, diffusion is the process by which molecules move from areas of higher concentration to areas of lower concentration in order to reach equilibrium. It is a passive process driven by the concentration gradient.
This process is called active transport, where cells use energy to move molecules against their concentration gradient, from an area of lower concentration to a higher concentration. This mechanism allows cells to maintain specific intracellular concentrations of certain molecules that are different from their surroundings.
Oxygen molecules move down a concentration gradient through simple diffusion. This means they move from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Diffusion of water molecules across a semipermeable membrane occurs through a process called osmosis. Osmosis is the movement of water molecules from an area of higher concentration to an area of lower concentration, through the semipermeable membrane, in order to equalize the concentration on both sides. This process is driven by the natural tendency of molecules to move from areas of high concentration to areas of low concentration until equilibrium is reached.

Diffusion describes the spread of molecules through random motion from regions of higher concentration to regions of lower concentration.
Diffusion describes the spread of molecules through random motion from regions of higher concentration to regions of lower concentration.
The higher concentration begins to diffuse into the area with lower concentration.
When molecules move down a concentration gradient, they naturally flow from an area of higher concentration to an area of lower concentration. This process is called passive diffusion and does not require energy input from the cell.
Diffusion describes the spread of molecules through random motion from regions of higher concentration to regions of lower concentration.
True. Osmosis is the process by which solvent molecules (usually water) move across a semi-permeable membrane from an area of higher concentration to an area of lower concentration in order to equalize the concentration on both sides of the membrane.

During diffusion molecules move from a region of higher concentration to one of lower concentration by random molecular motion.
