Question

Which property of water is most responsible
for water moving from the roots to the leaves
of a plant?
A. osmosis
B. adhesion
C. low boiling point
D. high specific heat

Answer 1

Answer:

The correct option is B.adhesion

Explanation:

A molecule of water is made up of a hydrogen atom and two oxygen atoms. The water is a polar molecule; hydrogen ions carrying a positive charge and oxygen atoms carrying negative charge. The negatively charged oxygen atom of one molecule will attract the positively charged hydrogen atom of another water molecule. Hence, developing the forces of adhesion or hydrogen bonds. This forces of adhesion pull the water upwards when water is lost by leaves through transpiration.
