Bio lab report introduction about photosynthesis

Hello I need assistance in writing an introduction for a lab report about photosynthesis.And the topics that need to be discussed in the discussion are:
what is photosynthesis? how it is formed? and what does it do?
what is a light reaction? how does it work? what does it do? and what are the main products of a light reaction?
what molecules are required as a reactant for the light reactions of photosynthesis?
How can you decrease or increase the intensity of light in an experiment?
what is Ethylenediaminetetraacetic acid (EDTA), sodium dodecyl sulfate (SDS), and Oxalic acid. and how might they affect the light reactions.
What is the inverse square law?
What are chloroplasts, Mitochondria, and endosymbiotic origin?
What is chlorophyll a, chlorophyll b, and carotenoids. And how does light affect them?
what is NADP?
