That process, called carbon fixation, resulted in the assembly of two three-carbon molecules called 3-phosphoglycerate (3-PGA). The energy stored in ATP and NADPH helps turn these 3-PGA molecules into ...

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 ...

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 ...

A colorized electron microscope image of a tomato leaf stoma. Credit ... a type of organelle found in plant cells. While ...

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 ...

Once water leaves the xylem, it moves across the bundle sheath cells surrounding the veins ... I. The role of stomata in sensing and driving environmental change. Nature 424, 901-908 (2003).

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 ...
