  • Photosynthetic Pigment Lab

    Identifying the Photosynthetic Pigments Introduction: This experiment was mostly introduced as identifying the different photosynthetic pigments between the Spinach and Blue-green algae. These two pigments were well used in this experiment and simply finding the appearances. Our group was to experiment both these pigments by the amount of bands there was to use, the distance between one band to another, the band color, the distance pigment migrated from the distance solvent front migrated, and lastly the pigment name. If we add the chromatography liquid to our pigments, then the extract of the pigment begin to separate onto the TLC plate. Materials: 50-mL Beakers Pencil 0.5 mL Blue-green extract 2 Pipet, graduated 4 mL Chromatography solvent 2 pipet, thin-stem 0.5 mL Spinach extract Ruler TLC plate (sheet) Scissors Marker or Wax 2 Watch Glasses Procedure: Label the two 50-mL beakers with group name or number, one beaker “spinach extract” and other “blue-green algae extract” Use scissors to cut the TLC sheet and…

  • Lab Report: What Happens During Photosynthesis

    during photosynthesis? What is the role of a photosynthetic pigment? Also, state your hypothesis, independent and dependent variable(s) in this experiment. Photosynthesis is the development of the process which all living plants get their food from the sun, plants absorbed them water from the roots, plants get their food from the sunlight, plants get help of water and carbon dioxide to survive and give out oxygen and take carbon dioxide. Purpose of this experiment is to analyze the different…

  • Spinacia Oleracea Synthesis Lab Report

    of photosynthesis. The energy used to drive the chemical reactions within photosynthesis comes from the sunlight absorbed by the chlorophyll molecules (Merzlyak, Chivkunova, Zhigalova, & Naqvi 2009). These chlorophyll molecules then transfer the light energy to chloroplasts and that light energy is converted into chemical energy (Merzlyak, Chivkunova, Zhigalova, & Naqvi 2009). The purpose of this experiment was to observe what the absorbance spectrum of Spinacia oleracea extract was and what…

  • Feast Of The Gods Analysis

    "The Feast of the Gods" is a master work of art created by an artist named Giovanni Bellini. This piece of art is an oil painting created during the Italian Renaissance in 1514 in Italy. The painting can now be found at the National Gallery of Art in Washington D.C. This painting used multiple elements of art, principle of designs, and has a historical meaning behind it. The Feast of the Gods is an oil painting. During the time of the creation of this painting pigments available to artist were…

  • Candle Lab

    because it has no (or least) amount of dye in it which will help it burn slower. My prediction is based on the fact that white candles are most given in emergencies(such as when they light goes out) so they are meant to last long and they are made with pure ingredients that contain no dye. Background Research Colour As candles are made with different types of dyes, I decided to find and research the most common types of dye used in candles. After researching I found out that their…

  • Tattoo Controversy In Our Society

    Not so long ago, May 1, 2014 Kevin who is a research scientist, studied many beauty products like a bar of soap in the shower. This time he did research on science behind tattoos. He found out that present days’ companies used pigments that are made of ion oxides (rust) that account for the black, red and browns. The formulas are Iron Oxide Red: Fe2O3, Iron Oxide Black: FeO · Fe2O3, and Iron Oxide Yellow: FeO(OH). For more exotic colors, heavy metals were used such as cadmium (red, orange,…

  • Pissarro's Painting 'Peasants In The Fields'

    Pissarro was a talented painter of the post-impressionist style era of art. In the oil on canvas painting Peasants in the Fields, Eragny it is shown that Pissarro is a revolutionary painter in the styles and techniques he uses. This one in particularly is done in a pointillism style of painting. This painting was also done in his late career when he started branching off into new directions and broadening his fields of style and techniques. He was a master painter that would draw from real life…

  • Hot Water Makes Things Lose It's Color Fast Than Cold Water

    water is really fast to dissolve materials because with it's own hotness, it melts materials really fast it also depends on how hot the water is if it is really hot than it can be really fast and if its warm it might just take more time than the really hot water. Cold water is like liquid ice and that should be really cold and that’s why it takes more time for it to dissolve materials slower. Pigment is a word that means color. Some objects lose their color faster than others. Some pigments…

  • Compare And Contrast Plant Pigment By Shirley Raps And Jeffrey Harborne

    In “Plant Pigment,” by Shirley Raps and Jeffrey Harborne, two types of plant pigments are discussed: photosynthetic and nonphotosynthetic pigments. Photosynthetic pigments are responsible for absorbing light and transferring energy during photosynthesis. Among this group of pigments are chlorophylls, phycobilins, carotenoids, and reaction center pigments which causes plants’ green, blue, yellow and orange colors, respectively. Nonphotosynthetic pigments are used to attract insects for…

  • Essay On Photosynthesis

    by-product in the process. This lab focuses on light-dependent reactions that occur in chloroplast where pigments absorb light through photosynthesis. Objective: The purpose of this lab is to extract photosynthetic pigments from spinach leaves using paper chromatography. We will then measure their absorbances at different frequencies using spectrophotometry. Hypothesis: I believe the rate of photosynthesis is controlled by the light the plant it receives and its temperature. Experimental…
