A structure formed from molecules that combine to make up cells is called an atom.
Answer: The correct answer is- Chlorophyll a.
Chlorophyll is a green pigment that is found in the chloroplast of green plants and algae.
Chlorophyll a is considered as the primary pigment for photosynthesis as it is present in all photosynthetic eukaryotes.
In the first phase of photosynthesis (formation of food using carbon dioxide and water in the presence of sunlight), which is a light dependent phase, chlorophyll absorbs the solar energy and converts it into chemical energy in the form of ATP, and NADPH.
This energy is further utilized in the next phase (that is a light independent phase of photosynthesis) in formation of food (glucose) .
