Passive Transport: Diffusion

BY: Mashi Molligoda

Active Transport

Active transport is the movement of particles across the Cell Membrane. This movement does not require any energy.


Diffusion is a TYPE of passive transport. Diffusion is when particles move from an area of high to low concentration. An example of diffusion is when you spray perfume (a few sprays) the perfume particles try to reach equal librium. Equal librium means that the particles try to spread out evenly across the room. As the particles try to reach equal librium they move from one to the other end of the room. So then the perfume can be smelled by the back of the room.
