The planets of the Solar System can be divided into two major groups: terrestrial planets and Jovian planets. In a 2 to 3 paragraph essay, describe three major differences between these two classes of planets, state what the solar nebula model is, and then explain why the solar nebula model accounts for these differences.

What is the name of the pigment that captures light directly in photosynthesis? (2 points)Why does the pigment appear green? (2 points) List two variables besides the wavelength (color) of light which might affect the rate of food production in plants. (4 points) Why is chlorophyll important for all biological life? (5 points) In Part I of the procedure, what is the name of the indicator used to identify the presence of CO2? (2 points)What color did the indicator turn after blowing air into the water through the straw? (2 points) What color did the indicator turn after the tube was placed under a light source for 30 minutes? (2 points) Why did this occur? (3 points) List the functions of these four common pigments found in plants. (4 points) Chlorophyll aChlorophyll bXanthophyllCarotene If the Rf factor of a pigment is .3750 and the distance that the solvent traveled is 8 cm, how far did the pigment travel? (5 points)List the Rf values for each of the pigments extracted from the spinach leaves, as seen in the chromatography procedure (4 points). CaroteneXanthophyllChlorophyll aChlorophyll b Based on the results, which pigment has the highest molecular weight? (5 points)From the chromatography lab, which pigments were soluble in the acetone? (5 points)The earth's early atmosphere did not contain oxygen. This changed dramatically once the early cells underwent photosynthesis. Explain how photosynthesis was able to occur in earth’s early atmosphere. (5 points)How did photosynthesis eventually affect the evolution of other organisms? (5 points) In reviewing the data from the floating disk experiment, which factor had a greater impact on the rate of photosynthesis (light intensity or concentration of carbon dioxide)? (5 points)Explain how you came to this conclusion? (5 points) **INFORMATION NEEDED TO COMPLETE THE FOLLOWING PROBLEMS**Independent Variable: This is the cause.Dependent Variable: This is the response or effect.One hundred samples of several different plants were placed in each of six sealed containers with water in them. At the end of two days the amount of oxygen produced was measured. Results are shown in the table below. Container Plant Height of Plant Light Intensity Source of Light Distance from Light ml O2 Produced 1 Iris 4" High Artificial 6" 16 2 Iris 4" High Natural 6" 13 3 Iris 6" Low Artificial 5" 12 4 Carnation 6" High Natural 4" 13 5 Carnation 6" Low Natural 4" 9 6 Carnation 4" Low Artificial 5" 14 Multiple Choice: Based on the data presented in the table, which two containers could be correctly used to compare the rate of photosynthesis at two different light intensities? (5 points) 1 and 22 and 31 and 55 and 64 and 5 Multiple Choice: Compare Containers 1 and 2. What independent variable is tested by this comparison? (5 points) Kind of plantHeight of plantLight intensityDistance from light sourceLight source Multiple Choice: Which container had the slowest rate of photosynthesis? (5 points) 123456 (Application) How might the information gained from this lab pertaining to photosynthesis and pigments be useful to you, or how can you apply this knowledge to your everyday life as a non-scientist? The application will be graded according to the rubric below. (20 points) Key components of critical thinking and application include the following:Demonstrates application and comprehension of the scientific principles.Displays competence in applying scientific knowledge to your personal or professional life.Relevant content is supported by facts, data, and detailed examples.The application paragraph is organized and structured. Critical Thinking and Application of Information 0% 1-49% 50-99% 100% Is your application a detailed description of how the lab content is relevant to your life? Application did not adequately demonstrate application or comprehension of the scientific principles. Did not include detailed examples, facts or data. Or the application was not included. A few areas of the application demonstrated some application and comprehension of the scientific principles by applying the knowledge to the student’s personal and professional life, but lacked detailed examples to support the content provided. Application demonstrated some organization and structure within the paragraph. Most areas of the application demonstrated evidence of critical thinking and comprehension of the scientific principles. Displayed good competence and the relevant content was supported with good use of examples that apply the concepts and describe how the information will be relevant and useful to the student’s personal or professional life. The application paragraph is primarily presented in an organized and structured manner. Application included a complete and detailed description of how the concepts are relevant and useful or applicable to the student’s personal or professional life. The application includes detailed examples and reveals insight into the scientific principles. The application paragraph maintains a strong sense of purpose and organization throughout.
