Abstract
Many environmental factors can contribute to a leaf’s stomatal density. The purpose of this experiment is to see how different light exposure in a leaf can affect the stomatal density of the leaf. The stomata allow the plant to regulate the intake and outtake of water and other molecules in order to maintain the plants temperature. Vinca minor leaves were gathered from an area that had a lot of shade and from an area that has a lot less shade and more sun in order to explore the stomatal density in the leaves of two different environments. The leaves were observed under a microscope and an average stomatal density of leaves in the shade and an average stomatal density of leaves in the sunlight were calculated. In the end, we concluded that there was no …show more content…
In future experiments we could look at other environmental factors such as temperature, relative humidity, etc. to see how stomatal density is affected. Plants grown in a colder environment versus plants grown in a warmer environment could be tested for stomatal density and I would predict that the plants in the warmer environment would have a greater stomatal density. Plants grown in a controlled environment with relative high humidity versus plants grown in a control environment with relative low humidity could also be tested for stomatal density; in this case I would predict that the plants in an environment with low humidity would have a greater stomatal density. We could also take a look at stomatal density in plants grown in a controlled environment of direct light vs plants grown in a controlled environment of limited light, I would expect results with better accuracy than the experiment conducted above because the amount of light exposure would be more tightly
