It does this through stomata. These are tiny holes in the leaf surface that can be opened and sealed shut using special 'guard' cells. If we can find out exactly how stomatal index relates to these ...

Plant stomata, which consist of paired guard cells placed on the surface of leaves, control gas exchange with the atmosphere. Anion transport by unidentified guard-cell channels closes the ...

But why, you might ask, might it be adaptive for a plant to control its rates of water loss and CO 2 uptake? One answer can be found in the sun. Generally, plant photosynthetic apparati are only ...

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 ...

Stomata, microscopic pores on plant leaves, regulate gas exchange and water loss by opening or closing in response to environmental cues. Guard cells surrounding each stoma regulate this process by ...

When stomatal lineage behavior is modified this alters not only stomatal numbers, but also numbers of non-stomatal cells. Thus, regulation of stomatal development is essential for formation of a leaf ...
