Spinach Chromatography Lab Report

1248 Words5 Pages

The purpose of the photosynthesis lab is to identify and observe the colors of pigments in a spinach leaf as they separate on chromatography paper. Photosynthesis is the anabolic process, or the process of making smaller particles into larger ones in metabolism, that plants use to convert reactants such as sunlight, water, and carbon dioxide into products of glucose and oxygen. Photosynthesis occurs in the chloroplasts of a plant cell where chlorophyll, a pigment, is used to allow the process to occur, while factors such as the amount of sunlight, water, and carbon dioxide affect how much photosynthesis occurs. Chromatography is the process of separating chemical mixtures by allowing chemicals to move over another substance (Woodford, 2017).The moving phase, or moving substance, is in one state of matter as it spreads across the stationary phase, or nonmoving substance, in another state of matter to be identified separately (Woodford, 2017). Chromatography works by adsorption, which means that as the molecules pass over the solid, the …show more content…

Pigments can be organic (containing carbon) or inorganic and are found in many materials such as spinach leaves. Spinach leaves contain chlorophyll a, chlorophyll b, beta-carotene, and xanthophylls, which are all types of pigments. (Fry, 2014). Chlorophyll a is blue-green, while chlorophyll b is bright green and both are used for photosynthesis in a plant cell (Fry, 2014). Beta-carotene is a pigment that ranges from red to yellow-orange and xanthophyll is the oxidized version of carotenes (Fry, 2014). The minor pigments play a secondary role in photosynthesis and transfer the energy the minor pigments receive back to chlorophyll for photosynthesis (Fry, 2014). If the spinach leaves’ pigments are separated by chromatography, then the pigments chlorophyll a, chlorophyll b, beta-carotene, and xanthophylls will appear on the chromatography

    The bands of color travel the greatest distance are more soluble than the bands that traveled less distance. In this experiment, we did not see chlorophyll a or carotenoids pigments. This could be due to the fact that we used coleus leaves and grass leaves, which do not have a large quantity of carotenoids or chlorophyll a. If we were to use spinach, then we would have seen a different concentration of pigments because the spinach leaf contains certain pigments at a higher

    Analysis: The chromatography paper revealed that chlorophyll a, chlorophyll b, carotenes, and xanthophylls, are present in a spinach leaf. This is because a plant needs several different types of pigments in order to photosynthesize properly while simultaneously protecting itself from the dangers of too much sunlight. Chlorophyll a is the primary photosynthetic pigment in all plants, however, all of the other pigments are important as well because they are the ones that provide extra layers of protection in order to shield the plant from harm. Discussion/conclusions: I accept my hypothesis because the data from the lab revealed that a spinach leaf does not only have chlorophyll, although that is all we can see with our naked eye, but also contains carotenes and xanthophylls that help to protect it. One thing I learned through this lab is that chlorophyll, although it is very important to the plant, it is not the only pigment that is important.

    Since the some of the sample used for these readings was lost, no additional dilutions were needed. Chlorophyll Determination: The absorbance at 652 nm was measured to determine the total number of chlorophyll a and b in the supernatant. At a wavelength of 652 nm, the two have the same absorbance and carotenoids do not absorb the light. The absorbance was 0.110 A, which was consistent with the standard. The concentration of the total chlorophyll was determined using Beer’s Law: mg/ml.

    The plant used in this lab was Phaseolus vulgaris, or the common bean. This plant does C3 photosynthesis. First, my partner and I got two pots with a bean plant in each. In order to get the most accurate and relevant results when compared to one another, the bean plants were relatively the same size. The plants beforehand each had two larger leaves, three smaller leaves, and three leaves in bud form.

    Because carbon dioxide is absorbed by the plant during photosynthesis less carbon dioxide present in the chamber is a sign that photosynthesis is working. The four lights used for this experiment range across the light spectrum on both sides in order to test a wider variety of wavelengths. All lights will be placed directly on the spinach leaf at the same distance so as not to give any spinach leaf a different light intensity, which could affect the data. This experiment will be able to show which light, ranging across the light spectrum, will allow the Spinach to perform photosynthesis more efficiently.

    How did different colors of light affect c02 consumption in spinach leaves? Background Photosynthesis is a process by which plants and other autotrophs make their own food using sunlight energy. Plants take in water, carbon dioxide, and use sunlight energy to create glucose and oxygen. Plants use the glucose as energy and release the oxygen as a by-product.

    (From Light Energy to Chemical Energy, Accessed 08 March 2018). Products to are made through photosynthesis as glucose is transported in to the plant as soluble sugars and stored as starch which is insoluble hence it is unable to escape from the cell. Although starch is able to revert back into glucose in order to release energy by respiration both useful for fats and oils for storage through the plant, proteins for growth and repair and cellulose for their cell walls.

    photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves.

    1. INTRODUCTION Lycopene is natural red color pigment that builds up of photochemical that mostly found in a red colored fruits or vegetables such as tomato, pink guava, watermelon, papaya and pink grapefruits. In 1876, Millardet was first who discovered this red pigment in tomato and later on, Schunck named it as lycopene (Kong, et al., 2010). It belongs to carotenoid group with lack of beta ionic terminal ring. Due to this, lycopene been known as not a pro-vitamin A carotenoid groups which cannot convert lycopene to vitamin A (Kelkel, et al., 2010).

After carefully observed the leaf by using the x65 lens, we puts a drop of salt into the leaf and closed the lid to see how the chloroplasts changed under the microscope. We were basically analyzing the changing of the chloroplasts shape after we puts the salt solution into the elodea leaf.

    They also contain xanthophyll which makes the leaves look yellow and carotene is what makes the leaves turn orange (Jensen, 2015). During the spring and summer the leaves on trees are green because of photosynthesis occurs. Photosynthesis is the progress of how leaves gets food and water (Jensen, 2015). The chlorophyll gets light from the sun and water from the ground, and then it turns into food and stores it in the leaf (Jensen, 2015).
