Passive Transport

Passive Transport

Cells need to move substances in and out to maintain balance and function properly. Passive transport is a process that allows molecules to move across the cell membrane without requiring energy. Instead, it relies on the natural movement of molecules from an area of high concentration to an area of low c...

Did you know that cells can move molecules in and out without using energy? This process is called passive transport.

A common example is simple diffusion, where small, uncharged molecules like oxygen and carbon dioxide move from areas of high concentration to low concentration.

For instance, when we breathe, the oxygen in the lungs...
