Yeah, X is a hard one, so we’re repeating. Have a look at this stump.
When the tree was in it’s last years alive, the Xylem was part of the living layer under the bark that ran the water (yesterday’s post!) up the tree to the leaves. SO even though this tress had rotted in the core, it still flourished because of its Xylem.
For more on Xylem, have a look-see at what I wrote last year!
