Soil! Although many plants live in soil, it is not exactly necassary for photosynthesis. Plants can actually grow in water instead of soil most times!

Hope this helps! : )

soil because that has to deal with roots, and photosynthesis happens in leaves. So the soil doesn't have anything to do with photosynthesis.
