Compare and contrast passive transport with active transport. Please have them in bulletpoints. Don't need to have full sentences.

both

both are systems that move water nutrients into cells and remove waste

passive

movement of molecules DOWN the concentration gradient ( no cellular energy needed)maintains an equal balance between water, gases, nutrients, etc...

active transport

uses ATP to pump molecules UP the concentration gradient ( requires cellular energy)  moves molecules through the cell membrane against the concentration gradientdisrupts the equal balance made by diffusion

The answer would be b. it is a learned trait
