Plant Pigmentation: A Study of Chromoplasts

How does the amount of caffeine and the duration of time of exercise affect the blood pressure and heart rate of different genders?

The purpose of this experiment was to measure the amounts of pigmentation for several different plants. The plants were made into a solution and the pigments were separated by paper chromatography. The pigments were then measured at different wavelengths by a spectrometer. The results were then put into tables and graphed. The information was also statistically analyzed and graphed again. The numbers were looked at qualitatively and interpreted. Each pigment has varying numbers of amounts for the different plants. Chlorophyll a has the most diverse range of values. The results show that the amounts the amounts of different pigments in the samples of Phylum Tracheophytes do vary. It is also shows that chlorophyll a being the main pigment also has the most wide spread values.
