During Diffusion Substances Move from an Area of?

During diffusion, substances move from an area of high concentration to an area of low concentration, until the concentration becomes equal throughout a space. Image showing the process of diffusion across the plasma membrane. Initially, the concentration of molecules is higher on the outside.

What substances move during diffusion?

Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

What is moved during diffusion?

Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. For cell transport, diffusion is the movement of small molecules across the cell membrane. ... The kinetic energy of the molecules results in random motion, causing diffusion.
