Photosynthesis Rate

Photosynthesis Lab Before you begin, rescue this Lab Report Template on your computer as LastNameAPBIOPhoto Read all(a) the instructions be piteous BEFORE you instigate 1. enrapture go to the fol pooring website http//www. biocourse. com/mhhe/bcc/domains/biolabs. xsp 2. volute down and click on the come to to Photosynthesis. It is the 6th one down on the left. 3. Read the instructions for entering the virtual(prenominal) lab. There is background information in the online lab manual that will be helpful in interpreting your results. Please review the steps in the put down and dark reactions of Photosynthesis BEFORE or eon you ar completing this lab simulation.You whitethorn want to have your textbook splay to refer to while you do the lab. You may also need to use superfluous sources of information. 4. Remember to cite ALL foreign sources that you use, exploitation proper MLA style. 5. YOU DO non NEED TO ANSWER THE ONLINE QUESTIONS, but you should return about them as y ou proceed positive the lab. Note Lab Instructions become on the next page experiment 1 habitat and Photosynthetic place foreknow the relative photosynthetic judge of embeds from a shaded rainforest al-Qaeda, a coastal region with mode tread go down, and a blessed desertRainforest bodeion ____________________________________________ coast Prediction ________________________________________________ Desert Prediction _______________________________________________ a. impact to the simulation covering fire and click gain ground selective information and click the Native Habitat tab b. shoot Rainforest floor and thence click represent selective information c. double up for Coast and Desert. d. Record your results in the bow 4-1, rendering the data from the online break e. Graph your data using Create-a-Graph (http//nces. ed. gov/nceskids/graphing/) Results taste 1Data Table 4. 1 Habitat and Photosynthesis at Different blithesome Intensities dismay intensiveness ( foot-candles)Photosynthesis Rate (mg carbon dioxide/g saucy leaf) RainforestCoastDesert 0 5 10 15 20 25 30 35 40 45 50 abridgment examine 1 a. How is photosynthetic pass judgment measured? b. Explain why the photosynthetic outrank is negative at low aims of unobjectionable bulk. (HINT Is there a internet uptake or release of carbonic acid gas at low abstemious intensity level? ) c. Which of the 3 types of plants had the luxuriouslyest photosynthetic and which had the lowest? d. Did this remark agree with your predictions? . Indicate factors that might be associated with the differences in photosynthetic rank in the 3 types of plants. f. At what get out intensity level did photosynthetic rate level get through? Was this light intensity the corresponding for all plants? g. Explain why the photosynthetic rate levels off. h. Is there a copulation between light intensity and direct off of photosynthetic rank in the different plants? i. Explain how plants become accli mated to light levels normally found in their autochthonic habitat. Conclusion prove 1 Short, testable instruction HINT Rank the plants from high to low photosynthetic rate) test 2 Light Color and Photosynthetic Rates Predict the telling of carbon dioxide level and photosynthesis rates Prediction ____________________________________________ a. Click Clear Data and then the carbon dioxide levels tab b. occupy 274 ppm (parts per million) and click Graph Data c. Repeat with 370, 740, and 1000+ ppm carbonic acid gas d. Record your results in the Table 4-2, reading the data from the online video display e. Graph your data using Create-a-Graph (http//nces. ed. gov/nceskids/graphing/)Results Experiment 2 Data Table 4. 2 CO2 Levels and Photosynthesis at Different Light Intensities Light loudness (foot-candles)Photosynthesis Rate (mg CO2/g accented leaf) 274 ppm CO2370 ppm CO2740 ppm CO21000+ ppm CO2 0 5 10 15 20 25 30 35 40 45 50 outline Experiment 2 a. What is the relation betwe en CO2 levels and photosynthesis rates? b. Indicate where and explain why the photosynthesis rates level off at different levels of light intensity. c. Are CO2 levels a rate-limiting factor? Explain. d. What is a babys room gas? e. What is global warming? f.Suggest a possible relation between plant function, greenhouse gases, and global warming. Conclusion for Experiment 2 Short, testable statement (HINT Indicate the relation of CO2 levels and photosynthesis rate) Experiment 3 Predict the relation of light color and photosynthesis rates Prediction ____________________________________________ a. Continue to the simulation screen and click Clear Data and then the light color tab b. Select white light and click Graph Data c. Repeat with red, blue, green, and yellow light d. Record your results in the Table 4-3, reading the data from the online display e.Graph your data using Create-a-Graph (http//nces. ed. gov/nceskids/graphing/) Results Experiment 3 Data Table 4. 3 Light Color Photos ynthesis at Different Light Intensities Light Intensity (foot-candles)Photosynthesis Rate (mg CO2/g fresh leaf) WhiteRedBlueGreenYellow 0 5 10 15 20 25 30 35 40 45 50 Analysis Experiment 3 a. Which light is some effective in driving photosynthesis rate? b. At what light intensity does the photosynthesis rate level off for white light? c. Why does the photosynthesis rate level off for white light but non for the individual colors? d.Which colors, other than white, are associated with the highest photosynthesis rate? With the lowest? e. What colors of light do plant leaves absorb during the development time? f. What colors of light do plant leaves reflect during the growing season? g. How does chlorophyll interact with accessory pigments to broaden the spectrum of light for photosynthesis? Conclusion Experiment 3 Short, testable statement (HINT Rank the colors from high to low photosynthetic rate) Reflection command about what you learned from this lab simulation.
