AP Bio Lab

However, the e pigments will eve up the chromatography paper at different rates because they are not e equally fat-soluble to the solvent. Photosynthesis has two main stages, the light-coloredheartedness reaction and the lightheartedness reaction. Light independent reactions occur only in the light a ND parent TAP and NADIA which are then used by the lightheartedness reactions to give the sack its pr access. Part B of this lab involves differing variables of light and carbon dioxide and the make they have on the rate of photosynthesis.In this experiment, the rate of photosynthesis will be assured through the floating of leaf disks in closure. Ill. Hypothesis, Materials, and Method classify A Hypothesis The plant will produce varying hardenings of color and yard pigment TTS along the chromatography paper. Part B Hypothesis The more light or carbon dioxide there is, the faster the rate of p Hottentots. IV.
