Word(s) of the Week: Phloem and Xylem
Today’s words are:
[phloem] and [xylem]
Pronounced: FLOW-um, ZYE-lum
Sciency Definition: Phloem and xylem are two layers of tissues found within the stems of plants and trunks of trees.
Or I could have said: Plant guts.
What’s it do? Phloem is made of tissues that transport sugars created during photosynthesis, feeding the plant from the top (where the leaves are) down to the roots. The xylem is made of tissues that transport water and minerals up from the root system. In trees, the xylem dies after one year, creating the rings you see in a tree’s cross-section.
Example sentence: A tree ain’t cryin’ without its XYLEM! Ha! Uh, sorry, I must have had some phloem stuck in my throat.
