The xylem of the plant stem performs several important functions. Elucidating the coordination or trade-offs between xylem functions is critical for understanding plant ecological strategy and ...

Vessels have diameters approximately that of a human hair and lengths typically measuring about 5 cm although some plant species contain vessels as long as 10 m. Xylem conduits begin as a series ...

As soil dries, plants limit water loss by closing tiny apertures called stomata in their leaves. A global analysis reveals ...

This research is based on previous studies dating back decades, such as Tyree and Sperry who reported (PDF) in 1989 on the vulnerability of the plant xylem (water transporting tissue) to ...

As water travels through the xylem in the stem and leaf, it is being replaced by water taken up by the roots. Photosynthesis produces glucose in the green parts of plants, which are often leaves.

Once absorbed, the polymer reorganized itself into an electrical wire that extended through the xylem, the system of water transport channels inside the rose’s stem. Add voltage, and the plant ...

Wood is an important building material, carbon store, climate proxy and, together with the phloem, enables the efficient transport of water, nutrients andmetabolites along plants’ axes. Secondary ...

"But the unique structures formed by 'xylem tracheary element' cells often fail to develop properly in these mutant plants, which causes the cells to collapse and ultimately reduces plant growth ...

A new method developed by Penn State biologists allows them to turn stripped-down plant cells into other types of cells, similar to the way stem cells differentiate into different cell types. Using ...

On the back of Xylem's (NYSE: XYL) latest quarterly earnings report, investors eagerly traded out of the stock on the second-to-last trading day of the week. This news-fueled decline left the ...

It forms a solid support. The phloem is towards the centre, outside the xylem. Any green part of a plant above ground, where it is exposed to light, can photosynthesise. But a plant’s leaves are ...
