Answer 1

Transpiration in plants requires adhesion of water molecules to cellulose, cohesion between water molecules, evaporation of water molecules and transport through tracheids. Cohesion between water molecules is as a result of hydrogen bonds between the oxygen atom of one water molecule and a hydrogen atom of another water molecule. Transpiration involves the release of water through the leaves in pores called stomata, this serves as a method of excretion of excess water and diffused gases.
