An international research team led by researchers at VIB-UGent has unraveled how the opening and closing of stomata—tiny pores on leaves—is regulated in response to high temperatures and drought.

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 ...

In this lab, stomata density variation likely results from interacting environmental factors (e.g. CO 2, temperature, water, etc.); therefore, higher stomata density might be consistent with a student ...

This magnified image of a fossilized Litsea calicarioides leaf clearly shows the stomata, through which leaves take in CO2 and release oxygen.

Scientists from Nagoya University have discovered a novel regulatory mechanism that controls the opening of stomata in plants, which is crucial for harnessing solar energy through photosynthesis.

To achieve this, the plant must allow CO 2 into the leaves, and allow oxygen and water (the waste products of photosynthesis) to escape. It does this through stomata. These are tiny holes in the leaf ...

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 ...

How do plants breathe through stomata? Key regulators of stomata are plant vacuoles, fluid-filled organelles bound by a single membrane called the tonoplast. Plant vacuoles are fluid-filled ...

On the lower half of the leaf are spongy mesophyll cells. These have air spaces between them to let gases flow. The stomata - tiny openings or pores – allow gases such as carbon dioxide and ...
