Plants adapt their water consumption to environmental conditions by counting and calculating environmental stimuli with their guard cells. Plants control their water consumption via adjustable pores ...

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 ...

Stomata are microscopic pores on the leaf surface that regulate gas exchange and water loss, balancing CO2 uptake for photosynthesis with transpiration. Each pore is flanked by a pair of guard cells ...

Every time the temperature drops, a cloud passes overhead, or the sun sets, a plant makes a choice: Keep its microscopic pores, called stomata, open to absorb carbon dioxide and continue ...

Left: A blue light pulse of 0.1 seconds triggers a calcium signal (red) in guard cells, which is followed by an anion current (black). Right: The influx of calcium into the cell promotes the release ...
