I want to know the answer to the following question:
Is sapwood the younger or older wood in a tree?
All the background I'm provided with is that "Sapwood (or alburnum) is the younger, outermost wood; in the growing tree it is living wood, and its principal functions are to conduct water from the roots to the leaves and to store up and give back according to the season the reserves prepared in the leaves.". Is that enough to answer the question?
Answer: yes
