Cornell researchers have discovered a previously unknown way plants regulate water that is so fundamental it may change plant biology textbooks—and open the door to breeding more drought-tolerant ...

correlation and causation: Many students do not understand the fundamental difference between correlation and causation. In this lab, stomata density variation likely results from interacting ...

Plants have tiny pores on their leaves called stomata—Greek for mouths—through which they take in carbon dioxide from the air and from which water evaporates. New work from the lab of Dominique ...

In this three week lab, students use the technique of making clear nail polish impressions of leaf stomata to generate and test an hypothesis of their choice about how leaf stomata density might vary ...
