Plant Pigment Chromatography VII. Analysis (Questions) 1. What factors are involved in the separation of pigments? Factors that are involved in the separation of pigments can include pigment solubility‚ the attraction between the pigments and paper and the size of each pigment particle. Because of these factors the results were as they were. Beta-carotene traveled the furthest because it forms no hydrogen bonds to the chromatography paper and is slightly soluble in the solvent. Contrastingly

experiment the pigments will rise up the filter paper once exposed to the water (solvent). After the experiment‚ it concludes that the mixture is a homogeneous mixture due to the chemical values equaling out with one another. Date:Tuesday‚ January 14‚ 2014 Purpose:The purpose of this experiment is to discover the various pigments isolated in the Expo Markers and to determine if they are homogenous or heterogenous mixtures. Observations: Data: Marker Color # of pigments observed

The effect of different wavelengths of light on photosynthesis rate in spinach leaves Abstract: This experiment was performed to test the effect of different wavelengths of light had on photosynthesis. According to the results gathered we can say that if two plants are put under different lights‚ one green and one a normal light‚ that the plant under the normal light will perform photosynthesis at a higher rate than the plant under the green light. This experiment is important because it shows

Red‚ blue‚ green‚ white‚ and no light were the sample subjects. Spinach leaf disks were collected and placed into a beaker‚ with ten leaves under each light specified wavelength‚ with bio-carbonate to release all the excess gases. When the gases were released the disks would float. The rate at which this occurred could

The process of photosynthesis requires an organelle called chloroplast and a pigment called chlorophyll The energy of the light is absorbed by chlorophyll and in turn supplies the plant with energy to transform carbon dioxide and water into oxygen and carbohydrates. (lab handout). The process of photosynthesis requires an organelle called chloroplast and a pigment called chlorophyll. Chlorophyll is a green pigment found in almost all plants‚ algae‚ and cyanobacteria that are critical for in

Investigation into the photosynthetic activity of isolated chloroplasts from spinach beet to various light conditions. Introduction Chlorophyll‚ an important pigment in chloroplasts‚ is an essential component in photosynthesis; converting electromagnetic radiation from the sun into potential chemical energy. Photons excite electrons in chlorophyll which move through the electron transport chain‚ resulting in energy being stored in the bonds of ATP and NADPH. The flow of electron through the electron
