correlation and causation: Many students do not understand the fundamental difference between correlation and causation. In this lab, stomata density variation likely results from interacting ...

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 ...

A magnified view of a stoma on the leaf of a Tradescantia albiflora albovittata plant, commonly known as a giant white inch plant. Animated GIF of a plant stoma opening and closing. A video of a ...

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 ...

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 ...

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.

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 ...
