In photosynthesis, chlorophyll functions in changing
a) glucose molecules to starch
b) water and carbon dioxide to sugar
c) light energy to chemical
d) hydrogen bonds to water

C) light energy to chemical

The chlorophyll traps the light, then converts it and uses it to chemical energy.

The chemical energy is used in the grana and lamella of the chloroplasts to change water and carbon dioxide into glucose and oxygen.

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
