For information on how this assignment will be graded‚ please visit the Course Information sectionChlorophyll and Accessory Pigments A pigment is any substance that absorbs light. The color we see comes from the wavelengths of light that reflect. Chlorophyll‚ the green pigment common to all photosynthetic cells‚ absorbs all wavelengths of visible light except green. The green reflects back to our eyes. Black pigments absorb

Column and Thin Layer Chromatography: The Separation of Spinach Pigment Abstract Spinach extract was separated into fractions containing compounds of similar polarity by column chromatography. Based on solid-liquid phase partitioning‚ this separation technique exploited the different polarity of the compounds in the spinach extract. Three fractions with different colors were obtained. The extract and its fractions were analyzed using thin layer chromatography (TLC). The TLC results showed that

Collecting Photosynthetic Rates in Spinach (Spinacia oleracea) Introduction: The purpose of this study was to see which light color would cause the spinach sample to photosynthesize the most within the given time. In order to understand photosynthesis‚ we need to know that chloroplasts absorb light energy from the sun‚ the plant then takes that energy along with water and carbon dioxide and changes it to sugar and oxygen. This happens in order for the plants to grow. But‚ light energy comes in a

conducted an experiment about the photosynthetic rate of spinach discs. We were hypothesizing that if we place all 6 individual cups underneath a different color of light‚ the spinach discs that produce enough oxygen will have the highest amount rise‚ which will show us the optimal color of light for photosynthesis. These different colors of light included blue‚ red‚ green‚ fluorescent‚ regular light‚ and classroom light. The classroom light was our control cup during the lab. Before we conducted our experiment

Benjamin Kleveland 502 October 26‚ 2014 Lab 7 Report Lights Distance and Wavelength Effect on Photosynthesis Photosynthesis and cellular respiration are often mistaken as the same thing. Although they are similar in many ways‚ photosynthesis and cellular respiration are the exact opposite of each other. Not figuratively‚ but literally the reverse (Photosynthesis). They incorporate the others products while adding some outside energy to create a never ending cycle. This brings us to the photochemical

observed from the results their photosynthetic pigment patterns using thin layer chromatography technique Introduction Endosymbiosis is a process where unicellular organisms engulf other cells resulting a life form that one or both cells are dependent on each other (Campbell et al.‚ 2008). Strong evidence suggests that different types of photosynthetic cyanobacteria underwent endosymbiosis that evolved into different types of photosynthetic eukaryotes (Biology 108 Lab Manual 2012).
