Xylem parenchyma | definition of xylem parenchyma by Medical dictionary
xylem parenchyma live plant cells that are short, lignified and generally thin walled. They surround conducting elements and assist directly or indirectly in the conduction of water upwards through vessels and tracheids, and also serve for food storage. They may be produced with other xylem vells at the end of the growing season.
