1. Can we determine the stomatal density on leaves collected in our local area?

This research focus question is intended to give directions to your study of stomatal densities and atmospheric levels of carbon dioxide. At this point we are trying to collaboratively develop as many local data points as we can. Looking at a lot of data will help us observe the relationship between leaf stomata and carbon dioxide, if there is one! Understanding what leaf stomata do and how do they allow the plant to interact with the environment is important knowledge to gain.

Working to answer the focus question, combined with the background information provided, and information that you develop on your own, should help us have a rich understanding of leaf stomata and their function. It is from this understanding that additional questions will emerge and drive the research.

With this focus questions guiding your work, proceed to the background information on global warming and leaf stomata.
