Passive transport does not require energy. This is movement of molecules down a concentration gradient. In order to maintain equilibrium, it goes from high to low concentration. Examples of passive transport include osmosis, diffusion, facilitated diffusion and filtration.
Active transport requires ATP to pump molecules up the concentration gradient. This occurs from low to high concentration. Movement of proteins, ions, large cells, and complex sugars requires active transport.
In short, the statement is TRUE.

I find it truly interesting how passive transport operates based on concentration gradients. The distinction highlighted between passive and active transport, particularly the significance of ATP, as discussed in this article, sheds light on the fundamental mechanisms at play.
