BIOLOGY LAB REPORT

hello 

i have a biology experiment attached can write for me the introduction, Materials &

Methods and the conclusion

 

Introduction: Defines the subject, the purpose of doing the experiment; includes some background information (usually can be gathered from the experiment’s intro); reader should be able to understand why the experiment was done, what you already know about the experiment, and the specific purpose of the experiment (usually stated in the title). Do not plagiarize your introduction or you will lose points!!! Also, citing is more than copying the work and listing the source! You must cite within the text as well. Your entire introduction cannot be cited!!! You will lose points for intros that don’t have your original thoughts. 

 

Materials & Methods: List the main materials used and write in your own words how the experiment is conducted; reader should understand what materials were used, how the materials were used, and what was actually done during the experiment. If the protocol was altered some way in class, you must make the changes in your lab report. Make sure you underline/italicize all microorganisms!!! Methods should be listed step by step vs. paragraph format. 

Conclusion:  answer questions at the end of the experiment, then discuss/conclude what your results mean in terms of the experiment and whether you were successful or not. The conclusion should not just state the experiment was successful, but definitive results should be explained here! Your conclusion should explain how the microbes used in the experiment were affected. For example, if the experiment is on gram staining, then your conclusion should state the gram reaction for each organism used. Ex: E.coli was determined to be gram negative, because it did not retain the purple of the primary stain, but retained the pink of the counter stain.

Biology Lab Report

Procedure I – Net Photosynthesis Rates – 100% Illumination

Complete the tables below using your data and information found under the Background tab (see the Summary of Needed Formulas section)

Observations and Questions

[1] Show your oxygen change rate calculation for the Sun-Adapted data run.

[2] Show your carbon dioxide change rate calculation for the Shade-Adapted data run.

[3] Examine your results. Do your results reveal a possible relationship between (rates of) production of oxygen and carbon dioxide? Explain. Cite your results as part of your explanation.

[4] Using your results for change in oxygen concentration as a reference, discuss whether your Procedure I results confirm research findings about differences in the amount of chlorophyll production for sun-adapted and shade-adapted leaves.

[5] How is the net photosynthesis rate related to the rates you determined? (note that this is not a calculation)

[6] Explain why (or why not) you would expect respiration to occur when the illumination is 100%?

Procedure II – Respiration Rates – 0% Illumination Data Run

Complete the tables below using your data and information found under the Background tab (see the Summary of Needed Formulas section)

Observations and Questions

[7] Sample Calculation: Show your oxygen change rate calculation for the Sun-Adapted data run.

[8] Sample Calculation: Show your carbon dioxide change rate calculation for the Shade-Adapted data run.

[9] Cite your results for the change in carbon dioxide concentration as a reference and compare the respiratory rates for sun-adapted and shade-adapted leaves. Explain the biological principles/bases underlying this comparison.

[10] What would be the photosynthesis rate if you measured it at 0% illumination in Procedure II? Explain your answer. Cite your results from Procedure I to assist with your explanation.

Procedure III – Low-Light Net Photosynthesis Rates – 15% Illumination

Complete the table below using your data and information found under the Background tab (see the Summary of Needed Formulas section)

Observations and Questions

[11] Sample Calculation: Show your oxygen change rate calculation for the Sun-Adapted data run.

[12] Based on the data you collected in Procedures I (100% illumination) and III (15% illumination), which system of leaves produces the most oxygen: Sun-adapted or shade-adapted? Explain how your results support your answer.

[13] Are your results from Procedure II and Procedure III consistent with research findings that there are differences in chlorophyll production and enzyme activity between shade-adapted leaves and sun-adapted leaves? Explain your reasoning. Cite your results from Procedure II and Procedure III to support your explanation.
