The surfaces of the leaves of many plants help to reduce water loss because they are not water-permeable. How does the biomolecule that makes up this surface differ from other biomolecules? It is made up of long chains of fatty acids.
It is made up of polymers of monosaccharides.
It is made up of long chains of nucleotides.
It is made up of polymers of amino acids.
