Movement of molecules from an area of high concentration to an area of low Molecules spread out over a large area. . Biology WKST (part 2) 9 Terms. is the movement of molecules from an area of high concentration to an low concentration until they reach a point at which they are spread are the substances which are dissolved into other substances called SOLVENTS.
Dissolved or gaseous substances have to pass through the cell membrane to get into or out of a cell. Diffusion is one of the processes that allows this to happen. Diffusion occurs when particles spread. They move from a region where they are in high concentration to a region where they are in low concentration.
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. The diffusion of water across a membrane because of a difference in concentration is called osmosis. osmosis, diffusion of water molecules across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration. Passive transport is called "passive" because it occurs WITHOUT. 30 seconds. Q. When molecules are spread evenly across the cell membrane, Low concentration, High concentration . Q. What does “high concentration area” mean?.
30 Jul - 3 min Diffusion: the movement of molecules from a region of high concentration to a region of low.
