Ap biology lab four: plant pigments and photosynthesis the purpose of this lab is to separate and identify pigments and other molecules within plant cells by a process called chromatography we will also be measuring the rate of photosynthesis in isolated chloroplasts. Ib biology higher level lab report title: investigate the effects of sodium bicarbonate and light intensity on the rate of photosynthesis of green spinach leaves through the observation of floating leaf discs. Ap biology photosynthesis lab bethany boyer due 11/12/14 lab write-up questions first experiment 1) the independent variable in this experiment was the presence of co2 (carbon dioxide) the dependent variable was the speed at which the leaf disks started to float.
Plant pigments and photosynthesis introduction: photosynthesis has two main parts, which are the light dependent and the light –independent in the light-dependent reactions pigments trap energy from light, and this energy is used to split water molecules (photolysis) the light-independent reactions or dark phase of photosynthesis involve the fixing of carbon dioxide. An action spectrum measures changes in some measure of photosynthetic activity (for example, o2 release) as the wavelength is varied ap biology forums anatomy test bank bio help genetic switch lab ap bio test format change tips for ap bio exam biology for the dat ap bio survival tips ap bio difficulty. The purpose of this experiment was to separate and insulate the different photosynthetic pigments, found on spinacia oleracea foliages and to pull out them utilizing the paper chromatography method. Photosynthesis is addressed in the topic outline of the college board ap biology course description guide as described below (lab based) i molecules & cells c cellular energetics photosynthesis 9 a major purpose of thylakoids that form the grana in chloroplasts is to (a) provide a fluid environment for the reactions in the light.

The purpose of this lab experiment was to separate plant pigments using paper chromatography, and to measure the rate of photosynthesis in isolated chloroplasts because of capillary action the solvent moves up the paper causing the pigments to become visible at certain distances. Labbench activity plant pigments and photosynthesis by theresa knapp holtzclaw introduction in photosynthesis, plant cells convert light energy into chemical energy that is stored in sugars and other organic compoundscritical to the process is chlorophyll, the primary photosynthetic pigment in chloroplasts this laboratory has two separate activities: i plant pigment chromatography, and ii.

Activities for example, water and macronutrients are used to synthesize new molecules, and, in plants, water is essential for photosynthesis organisms have evolved various mechanisms for accumulating sufficient quantities of water, ions, and other nutrients and transpiration ap biology lab manual • • • • • •. For this purpose, we recommend the analysis and discussion activities: photosynthesis this activity is based on investigation 5 in college board teacher manual for ap biology chapter 4 in the college board teacher manual for ap biology investigative labs. Paul andersen explains how pigments can be separated using chromatography he shows how you can calculate the rf value for each pigment he then explains how you can measure the rate of. Tip: my ap biology class just finished the aquatic productivity lab using a long-term computer interfacing setup we used ph probes to follow the carbonic acid (co2) levels over time (90 hours) in four miniature aquatic ecosystems.
