Four of the five answers listed below are related by their participation in water movement through plants. Select the exception.
A) hydrogen bonds
B) transpiration
C) cohesion
D) tension
E) phytoremediation
Phytoremediation
The use of plants to remove, degrade, or contain environmental pollutants from contaminated soil, water, or air.
Hydrogen Bonds
Weak bonds between partially positively charged hydrogen atoms and other partially negatively charged atoms, significant in the structure of water and biological molecules.
Transpiration
The pathway that water takes, moving from the roots to microscopic pores located on the leaf undersides, where it vaporizes and escapes into the surrounding air.
- Understand the dynamics of water transportation within plants, focusing on the mechanisms of transpiration and osmosis.

Final Answer :
E
Explanation :
Hydrogen bonds, transpiration, cohesion, and tension are all related to water movement through plants. Hydrogen bonds are the attractive forces between water molecules, which allows them to move as a cohesive unit through plant tissues. Transpiration is the process by which water evaporates from leaves, causing a negative pressure gradient that pulls water up the stem. Cohesion refers to the ability of water molecules to stick to other water molecules, allowing water to be pulled up the plant in a continuous stream. Tension is the negative pressure created as water is pulled up the plant through transpiration. Phytoremediation, on the other hand, is the use of plants to remove pollutants from soil or water and is not directly related to water movement through plants.
