Acknowledging these issues is the first step toward making the topic more approachable.. a. unique transcription factors that can only be found in stem cells. Most plants are green, so they reflect this colour and absorb other wavelengths, which they use for photosynthesis. pasteurization and sterilization quizlet labster. What are the photosynthetic pigments present in my leaf? Using paper chromatography to extract the pigments from leaves: --make extraction out of leaf --put spot of extraction on strip of paper until dried --put paper into solvent of ether (NON-POLAR), paper is POLAR because of large cellulose molecules For the land plants, there are two classes of these photosynthetic pigments, the chlorophylls and the carotenoids . Pigment Extraction: Use photosynthesis to produce biofuel and reduce pollution Relevant pigments using different solvents and measure their absorbance spectra to help a group of engineers figure out if a mysterious dark algae is able to absorb green light.
