heartwood and sapwood are formed due to
a)climatic changes which occur periodically
b)variation in water requirement of the tree with seasonal changes
c)variation in water requirement of the tree in spring and autumn
d)gradual non functioning of the wood progressively due to production of functional wood from the cambium outwards
Dear student,
Sapwood gives rise to heartwood as the tree matures.
Thus the correct answer is option D - gradual non functioning of the wood progressively due to production of functional wood from the cambium outwards
Regards.
| Sapwood | Heartwood |
| Formed due to the cambial activity of the secondary xylem. | Formed due to accumulation of different compounds, such as oils gums, and resins, etc. |
| Useful in water conduction | Lose their ability to conduct water. |
