This study's experimental data was used to create the newly improved stomata model introduced today. "We've known for decades that photosynthesis and stomatal opening are closely coordinated, but just ...

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 ...

Plant behavior may seem rather boring compared with the frenetic excesses of animals. Yet the lives of our vegetable friends, who tirelessly feed the entire biosphere (including us), are full of ...

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 ...

An astonishing new video shows plants “breathing” in real-time — and the footage could have huge implications for how farmers feed the world in the future. The close-up clip was captured by biologists ...

We are increasingly confronted with the impacts of climate change, with failed harvests being only one example. Addressing these challenges requires multifaceted approaches, including making plants ...

Most studies on stomatal responses to CO2 assume that guard cells respond only to intercellular CO2 concentration and are insensitive to the CO2 concentrations in the pore and outside the leaf. If ...

Scientists with two disparate sets of expertise -- in plant biology and protein structural chemistry -- have unraveled the atomic basis of how optimal numbers of stomata are made in leaves. Plants ...

video: A new computer model incorporates how microscopic pores on leaves may open in response to light--an advance that could help scientists create virtual plants to predict how higher temperatures ...

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 ...
