A lab about Chromotography an Chlorophyll

Biology: Chromatography and chlorophyll Analysis Questions and Observations: 1. 2 How many antithetical food coloring bands do you set on your chromatogram? Remember that each spot of color regardless if its the homogeneous color is an other(a) spot is a different pigment. (Note: that discolor at the scratch line point that remains is different from the other greens that ere dissolvable and moved with the solvent front) procedure the information to a lower place to help you identify the different pigments you perplex on your chromatogram. disposition them in your answer. Pigments Color chlorophyl a = Green chlorophyll b = Greenish-blue Carontenes = Orange Xanthophylls = Yellow I elate at that place are 5 different color bands I perceive the pigment from juice and 4 soluble pigments 2.Based total ly on the size of the spot/band, which pigment as the virtually gigantic? Greenish-Blue Analysis: 1.How do you know that plants do not arrange use of energy protons with wavelengths between 530-60nm? Because those wavelengths are what the plants lacks. It absorbs every color save those wavelengths, which to the human eye theorises the color not beingness absorb. 2.Summarize the conception/function of a photosynthetic pigment desire Chlorophyll a and b? What do they do and how do they dress? It absorbs sapless in blue and red regions and since light is a form of energy. The light transforms it to electrons and raises the molecule, which allows it to do photosynthesis. 3.According to the reading on the graph, what colors are actually absorbed but chlorophylls a and b? Chlorophyll a = ABSORBS VIOLET AND blushful and Chlorophyll b = ABSORBS BLUE AND RED REGION 4.Explain the purpose/advantages for a plant having both types of chlorophylls. Remember that a plant trust to d o photosynthesis. Its advantages is that it ! is able to do photosynthesis at night because its reflect the light in the...
