Hi there!
Active Transport - Through the use of ATP, active transport pumps molecules against a particular concentration gradient. Active transport occurs from a low concentration solute and moves to a high concentration of solute. Two examples of active transport would be endocytosis and exocytosis.
Passive Transport - Active transport is the movement of molecules down a gradient. Unlike passive transport, it goes from high to low concentration and does not require energy (such as cellular energy). Some examples would be osmosis and diffusion.
I hope this helped!
