An ostomy is a procedure in which a surgeon creates an opening, or stoma, from the inside of your body to the outside. This opening lets content bypass an area of the body that's injured or diseased.

Scientists have identified a natural compound, (Z)-3-hexenyl butyrate (HB), that can induce stomatal closure in plants, a ...

To avoid this, an individual plant may open its stomata and evaporate water which will lower the leaf temperature. Thus, one may hypothesize that leaves in the sun should have higher stomata density ...

Stomata are like windows on the surface of leaves: they close to prevent water vapour loss during transpiration, but open to allow CO 2 uptake for photosynthesis. The stomatal pore aperture ...

We want to create a record of how the atmosphere has changed through time by calculating the percentages of two different types of leaf cell (stomatal and epidermal) for many leaves, from the present ...

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

We study regulation of stomatal development and we are interested how environmental fluctuations modify this process at the molecular level. When stomatal lineage behavior is modified this alters not ...
