🧭 Cell Transport Overview Diagram

Painted membrane cross-section showing the three transport mechanisms simultaneously: diffusion (small molecules crossing freely through the bilayer), osmosis (water moving through aquaporin channels), and active transport (ATP-powered pumps moving particles against the gradient).

Quick Recall Flashcards

Define diffusion

The movement of particles from an area of high concentration to an area of low concentration down a concentration gradient. No energy is required (passive process).

Define osmosis

The movement of water molecules from an area of high water concentration (low solute concentration) to an area of low water concentration (high solute concentration) through a semi-permeable membrane.
