Comment
Develops as a response to gravity (tension) and may function in restoring a stem (PO:0009047) or branch (PO:0025073) that is leaning to its original position. Found in angiosperms. Secondary xylem tracheary elements (PO:0025445) in tension wood are often longer than the tracheary elements in non-tension wood of the same plant. The gelatinous fiber cells found in reaction wood have a cell wall inner layer (G layer) that contains abundant cellulose and is poor in lignin.
