Sentences with phrase «because stomata»

Because stomata of the plant usually close at night, water can squeeze out at the edges and tips of leaves, gathering in droplets.

Because the stomata (pores on the leaves) of many plants will close at night, water will attempt to squeeze out at the edges and tips of leaves.

Because stomata facilitate an efficient gas exchange with the atmosphere, they enabled the spread of plants and the subsequent evolution of our complex ecosystems.

Not exact matches

For this study, the researchers tested the sensors on a plant called the peace lily, which they chose in part because it has large stomata.

Plant biologists know that stomata open when exposed to light and close in darkness, but the dynamics of this opening and closing have been little studied because there hasn't been a good way to directly measure them in real time.

Because CO2 can aid the growth of plants — and close down stomata as well to protect against O3 invasion — it was unclear how vegetation worldwide would respond to such an increase in emissions of both CO2 and O3.

Surprisingly, these differences don't occur because grasses use unique stomata genes, but because they use the same genes as other plants in different ways.

The decision to study stomata in grasses was made not just because these plants are economically and environmentally important, but because grasses show several unique innovations that make their stomata much more efficient in taking up carbon dioxide while limiting water loss.

So those who want to sell anthropogenic global warming like the ice core records because they tell the «right» story, and those who want to discredit the theory pick the leaf stomata evidence, because that tells the «right» story.

Let's talk about what sex is like with a temporary stoma, because Crohn's disease is THAT MUCH FUN.

3) Some recent research indicates that enhanced CO2 availability increase the efficiency of water use by trees, because it's easier to pull sufficient amounts of the gas from the atmosphere without having to leave their stomata open and let water escape.

Happily enough, terrestrial also plants also require less water per unit of growth as CO2 rises because they don't have to open their stomata as much to get the respiratory exchange of gases.

It's because higher [CO2] reduces necessary stomata diameter for given CO2 transport, therefore reduces transpiration.

There is contamination of the air in the bubble by water; different results are obtained if the ice is crushed or melted to obtain the air sample; it takes decades for the air bubble to form; the raw data was smoothed out by a 70 year moving average that removed the great annual variability found in the 19th century and Stomata Index (SI) records; closer examination revealed a major flaw in the hypothesis because temperature rises before CO2.

Of course you know this already but you don't reveal that knowledge because it is contradictory to your personal views — just like the stomata data.

The trees were able to endure such low water potentials and maintain basal levels of metabolism because ecological forcings kept the tree density and leaf area index of the woodland low, physiological factors forced the stomata to close progressively and the trees were able to tap deeper water sources (below 0.6 m) than the grasses.

I have repeatedly pointed out (in several places including WUWT) that (1) ice core data are useful because they indicate CO2 concentration and isotope - derived temperature data from the same trapped gas bubbles but (2) ice core data are NOT a direct indication of anything because (2a) different ice cores provide different indications and (2b) other proxies (e.g. stomata data) provide different indications to those of the ice cores and to each other.

The patient, David James, had been admitted to hospital in May 2012 aged around 68 because of a problem with a stoma he had had fitted in 2001 during successful treatment for cancer of the colon.
