I am doing an ap biology lab on plant photosynthesis. It's specifically lab # 4 on plant pigments and photosynthesis and it's on question # 8 on Exercise 4B: Photosynthesis/ The Light Reaction.
Identify the function of each of the cuvettes.
I already have gone to the lab bench website where it explains the experiment but it doesn't give the answer to this question.
Look in the Cliff Notes AP Biology book
What reasons can you give for the difference in the percent transmittance between the live chloroplasts that were incubated in the light and those that were kept in the dark?
I found that each cuvette contained equal amounts of photosynthesis when the ultra-fertilizer is added to the solution, thus creating super-photosynthesis. Without the fertilizer only regular photosynthesis would occur and then nothing happens because no one really cares about regular photosynthesis anyways. You feels me?
To identify the function of each of the cuvettes in the lab, you will need to refer to the lab manual or instructions provided for the experiment. As an AI assistant, I don't have access to specific lab manuals or experiments. However, I can provide you with a general approach to finding the answer:
1. Review the lab manual or the instructions for Experiment 4B: Photosynthesis/The Light Reaction in your AP Biology textbook. Look for any specific information provided about the cuvettes.
2. Pay attention to any labeling or descriptions given for each cuvette in the lab instructions. The function of the cuvettes might be explicitly stated or implied.
3. Look for any clues in the procedure or setup of the experiment that indicate the purpose of each cuvette. Check for any differences in the contents or treatments of the cuvettes.
4. If the lab manual does not provide a clear answer, try discussing the question with your classmates or teacher. They may have additional information or insights that can help you determine the function of each cuvette.
Remember, the specific details of your lab experiment might differ from other sources, so it's important to refer to the instructions provided with your particular lab materials.
The objective of the lab is to see what is needed for photosynthesis to occur. Curvette 2 has everything we think it needs except light. So it is testing if light is necessary. Curvette 3 has everything we think is needed, so we are testing to see if that is true. Curvette four has boiled chloroplasts, so it is testing to see if the chloroplasts actually have to be biologically active to function. Curvette five is to see if any type of chloroplast are needed at all. Curvette 1 is a blank to set the spec at zero, so nothing except DPIP affects the transmittence. Next time you could talk to your teacher instead of looking for answers from some ramdon teen on-line. Who knows, I might be full of it.
Cuvette 1: Control factor
Cuvette 2: Bad conductor of photosynthesis
Cuvette 3: Good conductor of photosynthesis
Cuvette 4: Denaturation
Cuvette 5: Control Factor
