use the process of chromatography to separate plant pigments. To compare the plant pigments found in spinach and red leaf lettuce leaves. Hypotheses: I believe the spinach leaf in the acetone will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. I believe the spinach leaf in distilled water will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. Discussion Questions: 1. Describe

BEETROOT PIGMENTS - and membranes – These pigments are betalain pigments (not‚ as often thought‚ anthocyanins)‚ which they replace in some organisms. They are named after the Beet family of plants (Beta) but are also found in fungi (Fly Agaric - the red‚ spotted one!). In petals they presumably attract pollinating insects and may be present in seeds/fruits to encourage birds to eat them and so disperse the seeds. Man has selected for colour in beetroot‚ both because

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

Absorption spectrum of the Spinach Chloroplast By a Different Wavelength and Photosynthesizes Activity in different light filters Instructor: Dr‚ David Danseraveu Student: Hassan Sedaghat‚ A00345910 Due date: 11/13/2012 Material and Method: In the photosynthesis system‚ plants and other photosynthesizing creatures they use light of the sun as energy by absorbing some specific wavelength. A prepared sample of the chloroplast from spinach was used during this experiment

Experiment 5 Analysis of Plant Pigment Purpose: Chromatography is used for separation. In this case the separation of plant pigments. After placing the plant sample in the column the separation will be easy to see and the samples will be analyzed using VIS spectrophotometry. This is used to isolate and identify the different lipids causing the different pigmentations. Introduction: Lipids are chemically diverse substances found in cells. Lipids are water-insoluble‚ structural components

results did not support the hypothesis. Referring to table‚ one can see that blue caused both the spinach and radish plant to grow the most and that green light cause the plants to grow less. Spinach is a long-day plant therefore it was able to grow better under a constant light source. This would have aided in the plant growing faster than other forms of plant species. When experimenting with the spinach plant blue light worked exceedingly well in making the plant grow faster with there being a decent

Chromatography of Photosynthetic Pigments Abstract In this experiment a process of chromatography was used to separate chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and beta carotene. When these pigments were obtained they were used to measure the wavelengths by way of spectrophotometer of each and the total of all the pigments wavelength. Introduction Photosynthesis is a process by which plants use the sunlight to convert it from light energy into chemical energy. This equation shows us how

The History of Paint Pigments Chem 111-404 April 24‚ 2013 Introduction: This report expresses five different pigments that were formed during chemical reactions. Three out of the total five reactions went through a metathesis‚ or double-replacment reaction. A metathesis reaction can be defined as “a chemical reaction in which an element or radical in one compound exchanges places with another element or radical in another compound.” (Webster). The other two pigments underwent a neutralization

In this lab‚ we extracted spinach pigments‚ and analyzed what colors of light these pigments absorb. By using TLC plate‚ hexane and acetone‚ I separated the pigments of spinach‚ and discovered that the main pigments were green and yellow. This works because with different polarities‚ pigments move at different rates. Hexane and acetone were also used to separate chlorophyll and carotene from spinach. Since they are polar‚ they can separate organic and inorganic things. From the experiment‚ I know
