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 ...

Open (left) and closed (right) stomata found on the surface of plants' leaves, stems and other organs. Through the stomata, plants exchange oxygen and carbon dioxide, and lose more than 95 percent of ...

A doctoral student has identified a long-overlooked pattern in how plants evolved their equivalent of lungs -- tiny pores on the surfaces of leaves called stomata. Using specialized imaging techniques ...

Plants are those life-supporting systems that provide us with oxygen to help us breathe and produce food for consumption. These green living things surround us every day, be it in parks, crops in ...

How do plants breathe? When do they open and close the tiny pores on their leaves, and what does this mean for their water balance? A research team led by Marburg physicist Professor Martin Koch has ...

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 ...

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 ...

Plants obtain the water they need from the ground through their root systems. From there it travels to leaves, flowers, and fruits through a system of tubes. These tubes are called xylem. From the ...

In hot, dry weather, plants sacrifice their leaves to cool and protect flowers, which contain their sexual organs. The strategy could be harnessed to defend crop yields against climate change. Plants ...

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 ...
