Plants shape Earth’s atmosphere by moving carbon and water vapour. New research sheds light on how they learned to do it – and how it may change in future climates.

By understanding how ancient plants absorbed carbon and influenced climate, experts gain critical insight into how ecosystems might behave in our world.

The trees exchange carbon dioxide and oxygen with the atmosphere through little “mouths” in their leaves and tiny “windows” ...

Every time the temperature drops, a cloud passes overhead, or the sun sets, a plant makes a choice: Keep its microscopic pores, called stomata, open to absorb carbon dioxide and continue ...

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 ...

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 ...

This process is what scientists have dubbed photosynthesis. Photosynthesis starts with roots, stomata, and chloroplasts, biological structures found exclusively in plants. Most of us are familiar ...

Climate change has brought the extreme, erratic and unseasonal weather that’s now damaging and even killing our plants.  So we need to ...

Stomata are pores on the leaf surface that control gas exchange between leaves and the atmosphere. Stomata differ in shape, size, and number among and ...

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 ...

the radius is 0.20 mm. Area = πr 2 = 3.14 × 0.20 × 0.20 = 0.13 mm 2 The number of stomata in the field of view is 12.
