Explain how passive and active transport are similar and how they are different.

Active and passive transport are similar in that they both transport ions, using ion channels to move ions across the cell membrane. Active and passive transport are different in that active transportation requires energy, moves molecules against the concentration gradient, and may require an ion pump, while passive transport does not..

Explanation:

Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.
