The main role of chloroplasts<span> is to conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight and converts it and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water</span>
It is basically a structure which helps segregate the chormosomes in to the daughter cells
hope this was helpful
I need more to answer the question
ATP is an energy carrier that holds energy after processes like cellular respiration. The body can turn ATP into energy to do processes like physical movement later on.
Hope this helps :)
