|How does dust affect the rate of gas exchange in photosynthesis? This is relevant because plants near dirt roads are exposed to high concentrations of dust then those away from them. High concentrations of dust can inhibit necessary energy needed for photosynthesis.
|If plants are exposed to high concentrations of dust then the rate of photosynthesis will decrease due to the limited amount of sunlight able to reach the plant. Dust particles on the surface of the plant will reflect the light lowering the amount of sunlight able to reach chloroplasts in the...
|Create 3 closed systems with no dust in one (control) light dust in one and heavy in the last one. Add soil if needed to keep plants in place. O2 and CO2 percentages will be the variables monitored within each closed system. Keep all systems near each other to avoid temperature and light...
|If plants are exposed to high levels of dust then it will negatively affect gas exchange and the health of the plant. A possible explanation for this is the dust decreased stomatal conductance and lowered the amount of light the plant was able to absorb which reduced the rate of photosynthesis....
|About this Project
|Carter and Bryson worked diligently on their project involving dust and it's effects on photosynthesis gas exchange of oxygen and carbon dioxide. The project was relative to our area with their research question asking if dust affects the rate of photosynthesis when ATV's and other off road...
This is the last week of communication. I would like to say thank you for all the work you put in and the helpful guidance. Thank you for also making the more complicated things easier to understand and having interest in our project. Have a good holiday season and thank you again for all the help.
This may be the last time I get to say that but not everything is bad when saying goodbye. I just want to say thank you for all of the help and answers to all of the questions we had. We appreciate all you do and the leadership you have shown through this semester. We now have a better understanding on how sensitive plants are and how they respond to certain stresses. We also have a new understanding of what a scientist does and how different each one can be. I wish you the best with future education and wish you a successful career.
Thank you for the suggestion, we finished the new graph and have posted it. We were wondering if this one works?
We have posted a screenshot of our correlation calculations in files and we were wondering if it looks correct?
We were wondering your opinion on this idea, would doing a correlation with CO2 levels being the dependent variables and the scale of dust levels being the independent variable be okay? Or would there be a better way to go about doing a statistical test?
When we applied the dust it only hit the top side of the leaves and did not affect the underside where the stomata are located and the dust had the same effect on both plants no matter the amount. Our other thought was that dust only has an effect on gas exchange to a certain point and then past that point has no further effect on it.
We have finished our conclusion with claim-evidence-reasoning criteria and posted it above.
One of the things we noticed was that the container with no dust seemed to have more drastic fluctuations in gas levels compared to the heavy dust container. We also posted our finished table in the files section.
We have just finished collecting the data on the plants, hopefully we will have the table finished by today or tomorrow. Here are some pictures of plant health after the experiment.
We have attached the data from the first 18 hours of the experiment in the files and it shows how we will be collecting the data. We are taking 1 sample every 6 hours for five days.
We added a couple pictures of our experiment setup. We have started to collect data and hopefully by today we should have some of the table filled out.
