Which of the following best explains how water is able to move upward from the roots of a plant, through its xytem in the stem, and out to the leaves?
A. Water is polar, and the walls of the xylem are nonpolar. Water molecules have the ability to form hydrogen bonds with one another but not with the xylem
B. Water is nonpolar, and the walls of the xylem are polar. Water molecules are able to form hydrogen bonds with the xylem walls, and they are pulled up the
C. Water and the xylem are both nonpolar. Water molecules have the ability to form hydrogen bonds with one another but not with the xylem walls.
D. Water and the xylem are both polar. Water molecules have the ability to form hydrogen bonds with each other and with the walls of the xylem.
xylem.

water is able to move upward from the roots of a plant, through its xytem in the stem, and out to the leaves because Water and the xylem are both polar. Water molecules have the ability to form hydrogen bonds with each other and with the walls of the xylem and it is as a result of water covalently bonded to it's molecules which is as a result of unequal sharing of electrons, i.e slightly positive and slightly negative molecules on the side or partly ionic make water and xylem to form intermolecular associations with the wall of xylem which make water to move upward through its xylem in the root, stem.
