| 684156026 | transmembrane | water and solutes move out of one cell, make cytoplasmic contact, cross the cell wall, and into the neighboring cell. | 30 | |
| 684156027 | aquaporins | a transport protein in the plasma membrane of a plant or animal cell that specifically facilitates in water permeability | 31 | |
| 684156028 | Casparian strip | a belt in plant xylem made of waxy material impervious to water and dissolved minerals | 32 | |
