Movement of Materials in Cells - CliffsNotes

WebIf the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport. Consider substances that can easily diffuse through the lipid bilayer of the cell membrane, such as the gases oxygen (O 2) and carbon dioxide (CO 2 ). Webthe cell. These substances pass into or out of the cell by diffusion, using passive transport. Substances moving into the cell are needed by the cell, and substances moving out of the cell are not needed by the cell. Study the diagram below. Draw arrows in the diagram to show whether each substance will move into or out of the cell.
