Exploring photosynthesis involves understanding how plant pigments like chlorophyll and carotenoids capture light for energy conversion. Chromatography separates these pigments, while redox indicators like DCPIP and methylene blue reveal electron transfer rates in photosynthetic reactions. Factors such as light intensity, CO2 levels, and temperature are crucial in determining the efficiency of photosynthesis, with each having a potential limiting effect on the overall process.
