Question

water molecules travel from the roots to the leaves via hydrogen bonding. explain how this works using the following words: hydrogen bond, polar, cohesion

Explanation:

Water is a polar molecule, with a partial positive charge on hydrogen and partial negative on oxygen. Hydrogen bonds form between water molecules due to this polarity. Cohesion, the attraction between like - molecules, is a result of these hydrogen bonds. In plants, as water evaporates from the leaves (transpiration), the cohesive force of hydrogen - bonded water molecules allows a continuous column of water to be pulled up from the roots to the leaves.

Answer:

Water is polar, forming hydrogen bonds. Cohesion from these bonds enables water to travel from roots to leaves as water evaporates from leaves.
