organisms capable of making their own food. _ A small Rf value tells you that the pigment particles are less soluble in the solvent and tend to adhere. The wavelength is of fairly high energy.

Autotrophs are also called producers because they can use the energy in sunlight or chemicals to produce food. What color resume

Photosynthesis occurs inside a cell organelle called the chloroplast. The chloroplast contains green pigments called chlorophyll, which capture the energy in sunlight. The equation for photosynthesis is as follows: Light 6CO2 6H2O C6H12O6 6O2. What happened to your variable plants? Discussion: Do your results support your hypothesis? Why or why not? In doing an experiment scientists often begin to think about other questions. After doing your experiment, write down two questions you thought about while carrying out your experiment: 1. _ _ _ Which is more soluble in the chromatography solvent, xanthophylls or chlorophyll a? Xanthophylls _ Why did the plant extract appear green if yellow xanthophylls were present? _ The green light reflected by the chlorophyll is a more dominant color that masks the color. These are the things that plants need for photosynthesis: carbon dioxide water light These are the things that plants make by photosynthesis: glucose oxygen We can show photosynthesis in a word equation, where light energy is shown in brackets because it is not a substance: carbon. Now we are going to explore how autotrophs use the energy in sunlight to produce food. In the process of photosynthesis plants use the energy in sunlight to convert water and carbon dioxide into oxygen and high-energy carbohydrates. Calculate the R f values for each of the four pigments and record them in the table below. Use these values to identify each of the pigments (ask your instructor for the known Rf values). Place it in a beaker of hot ethanol for two minutes to remove most of the chlorophyll. (This breaks down the cellulose in the cell walls so that the ethanol can get into the cells and destroy chlorophyll and other pigments).
