Conclusion:

Results of the paper chromatography demonstrate that the chloroplasts of a spinach leaf contains of three types of plant pigments- chlorophyll a, chlorophyll b, and carotene. Researchers also conclude that among the three pigments, carotenes are the most non polar. Between the two chlorophylls, although they have similar polarity (attributed to their similar structures) their solubility varies. Chlorophyll b is less soluble than chlorophyll a. for part b, it can be conclude that the closer the plant with the source of light, the more the bubble that form. So photosynthesis need light to occur. For part c, two solution changed coloured.it stated that sunlight is needed and the presence of sun light for plant to do photosynthesis.
