What is a bark answer?

The bark is the outer hard part of the tree trunk. It refers to the tissues present on the outside of the cambium. They divide actively so that tree grows thicker. Lenticels are pores present on the bark which is responsible for gaseous exchange in woody plants.

What is a bark of a plant?

Bark comprises all the tissues surrounding the xylem in woody plants. Broadly, bark includes an inner and mostly living region and an outer, dead one. Of all plant structures, bark has the most complex anatomical structure and ontogenetic origin involving two (and often three) different meristems.May 23, 2019

What is bark made from?

Bark includes a cork layer of dead cells — the bark you see — and the cork cambium, made up of living cells. A layer deeper lies the inner bark, or phloem, which helps move sugars and other biomolecules through the tree.Jan 28, 2017

What is bark in trees?

B: The inner bark, or “phloem”, is pipeline through which food is passed to the rest of the tree. It lives for only a short time, then dies and turns to cork to become part of the protective outer bark. C: The cambium cell layer is the growing part of the trunk.
