The difference between alburnum and duramen is the presence of living cells.
Explanation:
- When there is a growth in the tree some changes will be associated with the trees.
- The main change is that the inner portions of the trees will become dark.
- Duramen or the heartwood forms the center portion of the trees and it is the central part of the trees.
- Alburnum or the sapwood will be light in color and it forms the peripheral part of the trees.
- The presence of the living cells in these two makes difference between them.
