SUMMARY
Water diffuses easily through the cell membrane due to the presence of specialized "gated" channels known as aquaporins, which facilitate the transport of H2O molecules. This discovery, recognized by the 2003 Nobel Prize in Chemistry, corrected the previous understanding that water passed solely through simple diffusion. The hydrophobic nature of the membrane restricts hydrophilic molecules, but aquaporins allow for efficient water movement across the membrane.
