WebJan 3, 2024 · Molecules move in and out of cells in one of three ways: passive diffusion, facilitated transport and active transport. Only a few small, relatively uncharged molecules can cross a membrane unassisted (i.e., by passive diffusion). Hydrophilic molecules that must enter or leave cells do so with help, i.e., by facilitated transport. Passive and ... great house paint colors https://laurrakamadre.com
