Show Answer

Answer:

Correct Answer: B

Solution:

Sapwood 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.

However, by the time they become competent to conduct water, all xylem tracheids and vessels have lost their cytoplasm and the cells are therefore functionally dead.

All wood in a tree is first formed as sapwood. They can be decayed faster if freely exposed to air So, the correct answer is ‘Sap wood’
