Water is the most abundant component in living organisms. Life on earth is inevitably linked to water. Water makes up 70% of human cell and upto 95% of mass of a plant cell (Figure 8.2).
Water is a tiny polar molecule and can readily pass through membranes. Two electronegative atoms of oxygen share a hydrogen bonds of two water molecule. Thus, they can stick together by cohesion and results in lattice formation (Figure 8.4).
• Adhesion and cohesion property
• High latent heat of vaporisation
• High melting and boiling point
• Universal solvent
• Specific heat capacity
