Grasses have top-notch border control to conserve water in their leaves. Now, scientists have identified the genetic switch that makes them such masters at taking in carbon dioxide without losing ...

New work from a joint team of plant biologists and ecologists has uncovered the factor behind an important innovation that makes grasses -- both the kind that make up native prairies and the kind ...

Stanford, CA -- 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 ...

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 ...

Scientists have created a new tool to watch plants breathe in real time. The new tech could help identify the genetic traits that make crops more resilient to global climate change, the researchers ...

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 ...
