Scientists remove chlorophyll from plants using extraction with an organic solvent. The solvent dissolves the chlorophyll while leaving other materials intact, according to Plant Methods.Know More
One of the common organic solvents scientists use to dissolve chlorophyll is acetone. The scientist begins by dipping the leaf into boiling water for a few seconds to a few minutes to stop other chemicals in the leaf from breaking down the chlorophyll. A student attempting this experiment as a science fair project should then cut the stems and veins from the leaf, saving the remaining tissue. The student then soaks the leaf material in pure acetone for several hours, until the solvent takes on a green color, indicating chlorophyll is dissolving from the leaves. Shaking occasionally speeds the process. The student pours off the liquid containing chlorophyll and discards the leftover leaf material.
The acetone solution contains chlorophyll, other pigments and other organic compounds. In order to further separate the extracted chlorophyll, the student paints a line of the concentrated acetone solution on a paper chromatography strip. He then suspends the strip with one end in the selected solvent to separate the green solution into various components. In a more advanced chemical laboratory, HPLC helps to separate the chlorophyll from the mixture.Learn More
Nitrogen is an essential component in chlorophyll, which is the pigment that provides green leaves and stems with their color. Nitrogen promotes vegetative growth in plants.Full Answer >
Leaves appear green because they contain chlorophyll. Chlorophyll absorbs the other colors of light wavelengths, leaving only the green reflected, and therefore visible to the human eye.Full Answer >
Leaves appear green because of the chlorophyll they contain. Chlorophyll is the part of the leaf that uses carbon dioxide, sunlight and water to produce sugar. A leaf with plenty of chlorophyll masks other pigment colors.Full Answer >
Chloroplasts are the organelles found in plant cells that contain chlorophyll and undergo photosynthesis. The chlorophyll pigments found in the chloroplasts are the main pigments utilized in photosynthetic reactions.Full Answer >
