Question

formation of secondary xylem.

Answer 1

Secondary xylem refers to the formation that occurs after the vascular cambium’s secondary growth. This type of xylem is not present in non-woody plants, but is commonly seen in shrubs and trees.

Secondary xylem consists of larger-sized vessels and tracheids. The cell walls of a secondary xylem are normally thickened by lignin deposition, which provides excellent mechanical support to the plant.
