The Research Question we will pursue for this guided research:

Organisms respond to the environment. One of the major environmental factors effecting plants is water loss from the plant tissue. Stomata play a role in water loss from the plant. If average annual rainfall in the growing season effects stomatal densities than in areas of different average annual rainfall during the growing season will we observe different stomatal densities?

So how did we come up this this research question?

Science depends on several assumptions about our universe; such as the universe has regular patterns that human beings can comprehend. Theories are the tentative explanations of our understanding of these patterns and how phenomena may operate in the universe. The pursuit of understanding requires that the researcher acquire and foster certain attitudes; such as questioning, disciplined curiosity, open-mindedness, with-holding judgment, respect for evidence balanced with skepticism, intellectual honesty, a sense of responsibility, and an understanding of one's competence and limitations.

Before planning an investigation, the researcher first recognizes a question or a problem to be studied. Although questions need not be derived from a theory, theories often guide researchers in predicting events or outcomes of research which ultimate ly support or deny the explanation. You have spent time investigating stomatal densities and you are ready to state a problem in a more formal manner. Questions about observable events related to leaf stomata are the basis of our work.

Research Ideas

Some interesting research area about leaf stomata would include:
• What is the normal variation found on a plant?
• The age of the tree and the number of stomata found on the leaf.
• The side, compass direction, of the tree the leaf comes from and the number of stomata found on the leaf.
• The direction of the slope the tree is growing on and the number of stomata found on the leaf.
• The difference in stomata on leaves grown in a carbon dioxide enriched environment to those grown under normal atmospheric conditions.
• Is there a clinal variation along a rainfall gradient?
• What is the variation in numbers of stomata that occur between plants growing in similar habitats but using different photosynthetic pathways, C3, C4, and CAM.
• Determination of diurnal (day/night cycle) and when stomata are open and closed.

As you have reviewed the information and worked with leaf stomata you may have come up with some of your own ideas for research. Your ideas should be added to this growing list of ideas.
