The effect of nitrogen supply on the transpiration rate and stomatal opening of potted bean plants was studied in a series of experiments. The transpiration rates of N-supplied plants were higher than ...

Stomata – the tiny pores through which plants take in carbon dioxide and give off oxygen and water – are closing up everywhere on earth as atmospheric CO2 levels rise. This change in plant structure ...

As carbon dioxide levels have risen during the last 150 years, the density of pores that allow plants to breathe has dwindled by 34 percent, restricting the amount of water vapor the plants release to ...

Scientists have discovered that certain plants can survive stressful, dry conditions by controlling water loss through their leaves without relying on their usual mechanism - tiny pores known as ...

A tiny, little-understood plant pore has enormous implications for weather forecasting, climate change, agriculture, hydrology, and more. Scientists have now overturned the conventional belief about ...

Most of the water that enters a plant will exit the leaf into the atmosphere. This provides a continuous stream of water which is known as the transpiration stream. Surface area (not an environmental ...
