what vascular tissue forms the bark, and what is the function of bark
Bark comprises all the tissues outside the vascular cambium of a vascular plant. The majority of the bark of woody plants develops from three meristems: the vascular cambium that gives rise to the secondary phloem, the phellogen that gives rise to the cork and dilatation meristem that produces parenchyma cells to avoid cracking when the axis increases in diameter.
the bark protcts the zylem and the phloem fron infection.bark is like our skin and if we cut off some of it and didnt keep it clean it would become infected.you could shave off a couple of inches and a tree may live depending on its age but if its a sapling and about 3 to 5 inches in diameter it would die eventually.
