Plants know how to do a neat trick. Through photosynthesis, they use sunlight and carbon dioxide to make food, belching out the oxygen that we breathe as a byproduct. This evolutionary innovation is ...

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 ...

New research in plants shows that a gene called MUTE is required for the formation of stomata -- the tiny pores that a critical for gas exchange, including releasing the oxygen gas that we breathe.
