The commenter continued that as time passes, the xylem and phloem (vascular tissues in plants that transport water, nutrients, and food throughout the plant) expand with the width of the tree ...

It's hard enough to accept that a tree that was a seedling before the ... in conditions that would strike fear into the phloem of virtually all other plants? After decades of intense study ...

High winds, heavy wet snow and significant ice have all been in recent weather headlines across Wisconsin. These weather ...

The vascular network consisting of phloem and xylem (wood) provides plants with structural support and long-distance transport that specifies further downstream processes in the sink tissues (such as ...

In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels.
