Riddle #8 – September 2022

Now that we’ve got that girth thing figured out, let’s take a closer look at this vital component of a tree trunk. That vascular or cork cambium produces conducting cells in two layers. What is the outer layer called and what its function? Ditto for the inner layer?

​Answer: The outer layer is phloem, sometimes referred to as the inner bark, the vascular tissue that conducts sugars and other metabolic products downward from the leaves.
The inner layer is xylem, located toward the inside of the cambium layer. Xylem is the vascular tissue through which most of the water and minerals of the tree are conducted.
