What type of transport does not require energy to move molecules across the plasma membrane?
concentration gradient
passive
bilayer
active

Passive transport

Explanation:

Passive transport can easily be described as transport of atoms, molecules or ions across the cell membrane without requiring energy. The capability of a system towards growing in entropy is the reason that passive transport does not require any cellular energy, unlike the active transport. The permeability of the cell membrane depicts the rate of transfer of molecules, ions or atoms by passive transport, into and out of the cell.
