Water travels from the soil to the root xylem through the apoplast (i.e., cell wall space) and/or cell-to-cell, but hydraulic barriers in the apoplast (e.g., suberized structures in the endodermis) can force water to traverse cell membranes at some points along this path. Anytime water crosses a cell membrane, its transport can be affected by the activ-ity of membrane-intrinsic water channel proteins (aquaporins). We review how aqua-porins can play an important role in affecting root water transport properties (hydraulic
Function [edit]. Aquaporins are the plumbing system for cells, said Agre. Every cell is primarily water. But the water doesnât just sit in the cell, it moves through it in a very organized way. The process occurs rapidly in tissues that have these aquaporins or water channels.. For many years, scientists assumed that water leaked through the cell membrane, and some water does. But the very rapid movement of water through some cells was not explained by this theory, said Agre.
