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
The Diffusion of Water- Osmosis. Like carbon dioxide and oxygen, water is able to move across the cell membrane from areas of high concentration to low concentration. This movement is aided by the presence of small channels created by proteins, which are called aquaporins.
