Unformatted text preview: AP BIOLOGY Blessed Trinity Formal Lab Report Format I. Title (5 points) The rate of photosynthesis and the separation of pigments in plants II. Problem (10 points) To separate the pigments in plants and to find the photosynthetic rates of plants at different light intensities and under different environmental conditions III. Background (20 points) Paper chromatography is a tool used to identify pigments and molecules from cell extracts. The solvent moves up the paper because the solvent attraction to the paper and to other solvent molecules. Different pigments are attracted to different fibers in the paper creating different rates in which they travel up the paper. In plants, chlorophyll a is the primary photosynthetic pigment. Chlorophyll a is located at the reaction center of photosystems so it needs chlorophyll b to aid it. Chlorophyll b captures light energy and transfers it to chlorophyll a. Light, used in photosynthesis, is a part of energy waves. The greatest amount of energy is found in the shorter wavelengths and the least amount of energy is found in the longer wavelengths. For example……. As leaf pigments absorb light, electrons within the photosystem are placed into higher example……....
