The question is asking to states and determine what takes place in organelles called chloroplast, base on my research, chlorophyll takes place which store photosynthesis in stacks of membrane called grana. I hope you are satisfied with my answer and feel free to ask for more if you have question and further clarification

Plants perform photosynthesis. They use the sunlight, that provides them with energy, and take the carbon dioxide from the atmosphere.

The main role of chloroplasts is to conduct photosynthesis.
They have chlorophyll, which is a green pigment that captures the energy from sunlight.

Photosynthesis  is a way for them to make their own food (sugars), necessary for them to stay alive and to produce oxygen.  Both will be needed for their cellular respiration, a process that occurs in the mitochondria, and will produce energy, in the form of ATP, and CO2.
