We did a lab about photoosynthesis. I need to write about how the light conditions affect the photosynthesis of spinach. I have the outline of the paper, and I have the 5 sources I need to use already. I just need to include them into my introduction. I have the instructions of what we did as a pictures as well as the set up. I also have the data. The data seems different and I would like to point that out in the discussion section. The set up was followed, so I dont know what could have caused our results to be different and negative. Also, it has to answer the questions in the rough draft announcement doc which is the instructions sheet. There needs to be in text cites and reference in APA. It needs to have one graph but I didnt make it but it can use the data table I already included.
