Certain monocots may very well be regarded trees beneath a slightly looser definition;[eight] even though the Joshua tree, bamboos and palms would not have secondary progress and under no circumstances generate legitimate wood with advancement rings,[9][10] they may create "pseudo-wood" by lignifying cells shaped by Most important growth.
The roots are, commonly, an underground Section of the tree, but some tree species have developed roots which are aerial. The common needs for aerial roots could be of two kinds, to add towards the mechanical steadiness on the tree, and to obtain oxygen from air.
