  • Properties
    • metabolite
    • solvent
    • high heat capacity
    • large latent heat of vaporisation
    • strong cohesion
  • Metabolite
    component of metabolic reactions including condensation and hydrolysis
  • Solvent
    Able to dissolve a wide range of substances
  • High heat capacity
    Water's ability to absorb and retain heat
  • Large latent heat of vaporisation

    Provides a cooling effect with little loss of water through evaporation
  • Strong cohesion
    produces surface tension highest cohesion of any non metal
  • Roles of water
    • solvent

  • Solvent properties
    • good at dissolving ions and polar molecules
    • able to dissolve a wide range of substances
  • Solvent examples

    • glucose dissolves in water and is stored in the vacuole
    • trees and plants take up minerals
    • bacteria cytosol is mainly water
  • Transport medium properties
    • substances dissolve
    • high cohesion

    xylem
  • Coolant properties
    • high temp stability
    • affected by temp
  • coolant examples
    frogs stay cool in summer and warm in winter
  • Habitat properties

    • ice is less dense, it floats
    • ice is insulating
  • Habitat examples
    • polar bears and seals have habitats
    • blue whales can still swim
