AP Bio Lab

However, the e pigments will eve up the chromatography paper at different steps because they ar not e equally soluble to the solvent. Photosynthesis has dickens main stages, the lightheartedness reaction and the lightheartedness reaction. Light independent reactions occur only in the light a ND unveil TAP and NADIA which are then used by the lightheartedness reactions to fuel its pr access. Part B of this lab involves differing variables of light and carbon dioxide and the effects they have on the roll of photosynthesis.In this experiment, the rate of photosynthesis will be assured through the floating of leaf disks in radical. Ill. Hypothesis, Materials, and Method part A Hypothesis The plant will produce varying bands of yellow and light-green 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. Variables Independent Variable Colors of the bands Dependent Variable Plant pigment part e Independent Variable Sodium bicarbonate solution Dependent Variable Time each disk took to floatControl Water/Soap solution without carbon dioxide V. Data and Observations. Part A Plant Pigments and Chromatography Observations The plant produced basketball team visible bands of color dark green, light green, green, light yellow and dark yellow. All of the bands were the same distance apart ex kept for band 4 and the solvent front which were both mm apart. Data Band Distance(mm) Band Color o. Scorn dark brown 2 1. Mm light green 3 2.
