Conclusion
​
For the project we collected samples of leaves, and data of the environment through the Lincoln Park area in Chicago, and we compared different variables we tested to learn how it would affect the stomatal density.
​
The purpose of the study was to find the correlation between certain environmental factors and tree characteristics with the stomatal density found in different tree species.
​
One thing we learned in this project based on our results is that our hypothesis was not totally correct. This is because we could see that the temperature and humidity does have am effect with the stomatal density in the leaves. The humidity, temperature and circumference impacted negatively the stomatal density. While the presence of diseases and size of the leaves impacted positively the stomatal density even if with the diseases the correlation was weak. With this said we can state that the hypothesis for the project was wrong about the influence on stomata of humidity, temperature, circumference, and diseases and the only thing that proved to be true was the influence of the size of the leaves over the stomatal density.
​
While we were collecting data for the project we also learned that certain factors may affect the structure of the leaves of the trees. Another thing we learned is that some trees are not apt for collecting data, because some may have some characteristics that may difficult the collection of data.
​
A new question that this research brings is: What are the mechanisms that the trees use to regulate the stomatal density?
​
To further the research in this topic it is necessary to keep collecting data through longer periods of time to get better conclusions.
