OBJECTIVES: The objective of this experiment was to extract plant leaf pigments and determining them by using the Rf values obtained from the paper chromatography technique. The hypothesis of the experiment was that all of the five listed pigments would be present in the extracted plant leaf according to the Rf values. PROCEDURE/APPARATUS: The equipments used were a 18 x 150 mm test tube with stopper‚ graduated cylinders‚ Erlenmeyer flask‚ mortar and pestle‚ metric ruler‚ tall jar‚ acetone‚ tiny

Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of photons‚ is actively captured by chlorophyll and related pigments present in photosynthetic organisms‚ like plants and algae. This captured energy is used to convert carbon dioxide into complex energy-rich molecules that can be used by themselves or other organisms. “Photosynthesis is the

pigments move at different rates. Hexane and acetone were also used to separate chlorophyll and carotene from spinach. Since they are polar‚ they can separate organic and inorganic things. From the experiment‚ I know that the pigments of spinach are mainly chlorophyll (green) and carotene (yellow). At first‚ I thought that they absorb the color which they present to us (the color we see of them). For example‚ I thought chlorophyll absorbs green light because

The green leaves Leaves look green because of the chemical chlorophyll. The other reason is that they reflect light in the green spectrum. Chlorophyll absorbs light most strongly in the blue portion of the spectrum‚ and then some in the red portion. Leaves receive their green color during the process of trying to absorb energy from the sun. The sunlight strikes the leaves‚ which contain chlorophyll‚ and the chlorophyll reacts by emitting the green color. Leaves are green because that is the

(hydroponics) is one of those solutions; soil becomes unnecessary in agriculture by that process. Other materials such as perlite‚ gravel‚ clay or Styrofoam is used instead of soil. Fe is an indispensable matter for plant grows as it takes place in chlorophyll synthesis reactions. Therefore it must be given to plants in an optimum ratio and different amount of Fe will cause different results in a plant. The objective of the study is to investigate whether are the different amounts of Fe effective at increasing

This conversion into chemical energy is associated with the action of the green pigment chlorophyll. Chlorophyll molecules located in the thylakoid membrane of the chloroplasts are arranged into complexes known as photosystems. Each photosystem contains the reaction center complex and is surrounded by light harvesting complexes. The light harvesting complexes are composed of pigment molecules such as chlorophyll a‚ b and accessory pigments that broaden the spectrum of light absorbed for photosynthesis

The purpose of this experiment was to demonstrate the presence of carotenes‚ xanthophylls‚ and chlorophylls in leaves. Methods and Materials. A piece of Whatman #1 filter paper was cut to fit into an ignition tube. One end was cut to form a V‚ and the sides of the filter paper were made sure to not touch the sides of the ignition tube.

of gem corn which is produced as a result of selective breeding. Anyways‚ most plants require light in order to grow and conduct photosynthesis. Plants that have been previously grown in the dark are incapable of photosynthesis since they lack chlorophyll and many polypeptides needed for light harvesting. But once they have been exposed to light‚ over time‚ reorganization of the plastid membranes occur and all the required enzymes and proteins needed for photosynthesis appear. So undetectable levels

The data found in this experiment supported the initial statement in the hypothesis‚ that blue would have the highest rate of photosynthesis (see Figure 7). The second part of the prediction was refuted by the data‚ as green had a higher rate than both yellow and red. This result seems to go against the experiment‚ however the answer is in Figure 5. When adding green food coloring to the solution (see Methods) dilution also took place. When comparing the wavelength of 540 nm (see Tables 1 & 2) with
