This Concept Map, created with IHMC CmapTools, has information related to: Chapter 8, Labs ???? Leaf Chromatography Lab, Analogies ???? Photosynthesis = Battery [Batteries contain chemical energy, transportable, & storable], Results ???? Leaf with Most Visible Pigments - Equal Amount on Both Leaves, Quantitative ???? Rf Value of the Croton Leaf Xanthophyll - .706 Cholorphyll - .141 Anthrocyns - .271, Analogies ???? Priestly:Oxygen By-Product as Mayer:Chemical Energy, Procedures step three 3.Use the glass rod to put some of the pigment extract on the pencil line. Let it dry., Scientists ???? Melvin Calvin - Calvin Cycle (chemical path that carbon follows to from glucose), Chapter 8: Photosynthesis ???? Scientists, Analogies ???? Photons:Phtosynthesis as Key:Car, Leaf Chromatography Lab purpose of To observe the pigments that give a leaf its color To analzye data obtained from paper chromatography, Data ???? Quantitative, Qualitative ???? Carotene was not visible on the chromatography paper for niether the spinach nor croton leaves, Leaf Chromatography Lab ???? Data, Scientists ???? Julius Robert Mayer - plants convert light energy into chemical energy, Procedures step one 1.Cut a piece of chromatography/filter paper so that it fits inside of the test tube. Cut a point at one end. Draw a pencil line about an inch and a half above the point. Bend a paper clip so that it attaches to the cork and the paper. The paper should hang inside the tet tube., Results ???? Most Visible Pigments - Xanthophyll, Analogies ???? Glucose:Dollar Bill ATP:Pennies Cellular Activities:Gumball Machine, Analogies ???? Calvin:Dark Cycle as Marcus:ETC, Analogies ???? Chlorophyll:Infield as Assessory Pigments:Outfield, Scientists ???? Jan van Helmont - trees gain most of their mass from water
