Question

What process exerts the pull on water molecules that is relayed from leaf to root via cohesion?

Answer 1

Transpiration utilizes a pull that is relayed downward along a string of water molecules held together by cohesion and helped upward by adhesion. A plant's xylem tissue is enhanced to use outside forces to move water and dissolved materials from its roots to its shoots.

Answer 2

Answer;

Evaporation

Explanation;

-Evaporation is the process exerts the pull on water molecules that is relayed from leaf to root via cohesion. Cohesion is the attraction between molecules of the same substance such as water, it helps the transport of water and dissolved nutrients against gravity in plants. Conversely, adhesion is the attraction between molecules of the different substance helps counter the downward pull of gravity.
