Anna11 [10]

Harman [31]

Answer:

Explanation:

Cohesive behavior can be explained as a behavior where molecules are attracted to each other.

In this case, it is believed that the water molecules behave this  way because they are polar, that is, there is an electronegativity difference between the bonded atoms. And this enables it to move from the roots to the leaves of the plants.
