Hi,

This set of powerpoint slides cover more on organic molecules in organisms.

• the polar nature of water molecule giving rise to many uses and properties in organisms
• high heat capacity, high latent heat of vaporisation, solubility, capillary action and transpiration pull in xylem vessels
• magnesium ions in plants for making chlorophyll
  
• nitrate ions in plants for making amino acids from glucose
• uses of carbohydrates, mono-, di- and polysaccharides
  
• uses of lipids in body and their structures
  
• uses of proteins in body and their structures
