Answer:
Both Cohesion and adhesion play an important role in the upward movement of water through a plant.
Explanation:
Water is absorbed by the roots and transported by xylem tissue to various parts of a plant body such as stem ,leaf .
During the transportation of water molecules through the xylem tissue formation of hydrogen bond occur between the water molecules. A single hydrogen bond is weak but collectively they exert a very strong interaction.As a result a water column is established in the xylem tissue. This is called cohesion.
Adhesion deals with the interaction of water column with the wall of the xylem tissue.
<span>The correct answer is B.Too much water moved into the cell. Similar things happen to our bodies, if there's too much water the body deforms because it becomes bloated. If there's too little water the body deforms and becomes smaller because there's no water so the skin shrinks a bit but it's barely noticable.</span>
