In the context of cell transport, what is the main difference between active transport and passive transport?

• Active transport requires energy, while passive transport does not.

• Passive transport requires energy, while active transport does not.

• Active transport can only move materials out of the cell, while passive transport can move materials in both directions.

• Passive transport can only move materials into the cell, while active transport can move materials in both directions.
