Title of Experiment Extraction of Spinach Date that the Experiment was Performed This experiment was performed on Wednesday‚ September 17th‚ 2014 at 2:45 pm in the St Ignatius Science Center Laboratory 323. Partners Names Taylor Jackson and Matt D’Angelo. Taylor‚ Matt‚ and I shared the same data. Purpose/Goals/Objectives The purpose of this experiment was for each student to use column chromatography to separate plant pigments from spinach leaves. Some goals and objectives were to

take spinach leaves and extract the chlorophyll and carotenoid pigments by using acetone as the solvent. The chlorophyll and carotenoid pigments were extracted by using column chromography and alumina was used as the solvent. Solvents of different polarities were used‚ starting with the least polar‚ to extract the certain components from the leaves. They were then analyzed by using thin- layer chromatography. Procedure: The first part of the experiment dealt with breaking down the spinach leaves

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

three smaller experiments as a result of the different properties chlorophylls possess and the need to test them individually to receive the most accurate results. Preparation for the lab began with selecting a medium to large spinach leaf and deveining it. Once the spinach was prepared‚ it was ground in 5 mL of 100% acetone‚ creating a green acetone extract. The extract was filtered through a funnel with a kimwipe and into a test tube. The volume of the filtered extract was estimated‚ and one half

the Extraction lab is to separate and purify benzoic acid‚ 2-naphthol‚ and naphthalene. These organic solids are purified by partitioning the solid in 2 immiscible solvents‚ diethyl ether and sodium bicarbonate or sodium hydroxide. II. Significance a. The significance of the Extraction lab is to purify Acetanilide benzoic acid‚ 2-naphthol‚ and naphthalene by determining the partition coefficient. This value is determined by dividing the solubility of the given solute in the extraction solvent

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

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
