fast green stock solution and chloroplast pigments‚ information about high absorbency wavelengths was gained. By plotting this information in an “absorption spectrum” graph‚ the maximum absorption was easily identified for fast green‚ chlorophyll A and chlorophyll B (refer to figures 1 and 4 within this lab). The graphs in general can be closely related and compared to Beer’s Law stated above. For example‚ when referring to figure 2 (within this lab) concentration curve for fast green‚ absorption

From this experiment‚ I found that the ratios of chlorophyll: carotenoids: DNA: RNA: protein in Euglena cells were 1.000: 0.198: 4.254: 1.950: 37.017‚ respectively. The standard ratios of chlorophyll: carotenoids: DNA: RNA: protein are 1.00: 0.60: 5.00: 38.00: 446.00‚ respectively. By comparing the results‚ one will agree that the experimental order of abundance of each component

Introduction The purpose of this experiment is to determine the maximum absorbance of fast green‚ and the chlorophylls‚ also in the case of fast green create a concentration curve to determine an unknown substance. Each test will use the spectrophotometer. Spectroscopy is the study of light. A spectrophotometer is a machine used to determine the absorbance of light at any given wavelength. It does this by using a source of white light through a prism‚ which gives multiple wavelengths that

a plant have chloroplasts. However‚ the leaves are the major site of photosynthesis for most plants. There are about half a million chloroplasts per square millimeter of leaf surface. The color of a leaf comes from chlorophyll‚ the green pigment in the chloroplasts. Chlorophyll plays an important role in the absorption of light energy during photosynthesis. Chloroplasts are found mainly in mesophyll cells forming the tissues in the interior of the leaf. O2 exits and CO2 enters the leaf through

During eukaryotic evolution‚ red algae and green algae led to five supergroups of eukaryotes through a process of secondary endosymbiosis (Campbell et al.‚ 2008). Three basic photosynthetic pigments: chlorophylls‚ carotenoids‚ and phycobilins‚ each absorb light at different wavelengths due to different colors and different

one of the so-called green foods that are valued by heath-conscious individuals as a great natural source of nutrients. Wheatgrass‚ available in fresh juice form or from tablets is high in chlorophyll‚ calcium‚ magnesium and potassium.It is wheatgrass’ chlorophyll that is perhaps its most valuable asset. Chlorophyll‚ the plants green pigment that is often referred to as the "blood of plant‚" has been shown in studies to have a cleansing‚ detoxifying and healing effect on the body.Wheatgrass‚ is grown

will separate in this order: Chlorophyll A‚ Chlorophyll B‚ Carotene‚ and Xanthophyll. Introduction Chlorophyll is the molecule that absorbs sunlight and uses its energy to synthesize carbohydrates from CO2 and water. This process is known as photosynthesis and is the basis for sustaining the life processes of all plants. Since animals and humans obtain their food supply by eating plants‚ photosynthesis can be said to be the source of our life also. As the chlorophyll in leaves decays in the autumn

Four different pigments were examined from the spinach leaf: chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and carotene. Based upon looking at the pigments individual molecule structures‚ our group hypothesized that the most polar molecule‚ chlorophyll b‚ would travel the shortest amount up the chromatography paper‚ and the least polar pigment‚ carotene‚ would travel the furthest up the chromatography paper

color of light also has an effect of the rate of photosynthesis. The red light resulted in the greatest amount of oxygen produced and the blue was not too far behind. Green produced the lowest amount of oxygen because that is the only color the chlorophyll does not absorb. It also has longer wavelengths than the blue and red light. The results demonstrate that the wavelengths of light relate to the rate of photosynthesis and the shorter the wavelength the higher the rate. If yellow bulbs were used
