Jamie Milano Biology 150 Photosynthesis Homework April 8‚ 2013 Reviewing Your Knowledge 2. A pigment solution contains compound A with 4 polar groups and compound B with 2 polar groups. You plan to separate these compounds using paper chromatography with a non-polar solvent. Predict the location of the two bands relative to the solvent front. Explain your answer. Since compound A is probably more polar than compound B‚ compound B will move further in the chromatography. Since the solvent is non-polar

What is light? Pigments absorb light‚ which drives photosynthesis. Photosynthesis requires both photochemical and biochemical reactions to produce sugars. Chloroplasts are the site of photosynthesis in plants. The light reactions of photosynthesis produce ATP. The

experiment. My Hypothesis for this experiment was to found out the amount of pigment loss of beetroot when exposed to varying temperatures. Betalain pigment found in beetroot My method for this experiment is:- * Use a cork borer to cut about 3 cores of fresh beetroot approximately 8mm in length. * Place them with the help of a forcep on a tile and trim so that it is about 1mm in length. While doing this make sure that no pigment is lost from the beetroot. To trim the beetroot cores in equal pieces I

LABORATORY REPORT FOR BIO411 Experiment 5 : Cellular Respiration Experiment 6 : Photosynthesis Title: Cellular Respiration Objective: To observe and determine cellular respiration in yeast/onion cells. * Measure respiration rate using different substrates. * Measure respiration rate at different temperature. Introduction: In this laboratory experiment‚ we are given 3 task. The first one is respiration in yeast. Second is respiratory indicator and the third one is observing

namely‚ pigments (titanium dioxide‚ zinc oxide etc.)‚ solvents (mineral turpentine) and resins and additives. Pigments are finely ground solids of different shades to give colour‚ durability‚ consistency and other properties to paint. It is also one of the major raw materials‚ accounting for one-third of the total raw materials cost. Amongst the vital pigments used in the process of paint manufacture is Titanium dioxide (TiO2) and the industry consumes around 60% of TiO2. This pigment is available

through the use of a beetroot. I predict that as the temperature of the water increases so will the dispersion of the pigment. Independent Variable: The temperature of water will be increased in increments of 10oC‚ thus the temperatures I will be using are 20oC‚ 30oC‚ 40oC‚ 50oC and 60oC. Dependent Variable: I will be measuring the cell membrane permeability through the amount of pigment dispersion. A colorimeter will be used to quantify results into a percentage transmission of light‚ after it is left
