Vedclass · Answer

(A) Water is a polar molecule and forms hydrogen bonds between the positively charged hydrogen atoms and the negatively charged oxygen atom.Hydrogen bonds cause water molecules to stick together,a property known as cohesion.When water molecules form hydrogen bonds with other surfaces,such as the cell walls of xylem vessels,it is called adhesion.These cohesive forces allow water molecules to be pulled upward as a continuous column during transpiration.

According to the transpiration-cohesion theory,the upward pull of water is transmitted to other water molecules by cohesion,which is caused by
