Scientists have uncovered how the interplay between cell shape and mechanical stress influences the orientation of stomata ...

For centuries, scientists have known that plants "breathe" through microscopic pores on their leaves called stomata. These tiny valves are the gatekeepers that balance the intake of carbon dioxide ...

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 ...

Brassinosteroids, a class of plant hormones, play an important role in determining the number of leaf stomata, but the underlying mechanism was until now not well understood. Brassinosteroids are ...

Plants constantly make trade-offs in their decisions: more light means more opportunity for photosynthesis, but then hot temperatures and dry air makes wilting more likely. Stomata - microscopic ...

As global temperatures rise and regions become exposed to increasingly extreme conditions such as droughts, the need for hardy, water-efficient crops grows. Through the study of leaf stomata, research ...
