The soft, light-colored wood found just beneath the bark of a tree, which is responsible for transporting water and nutrients.
The alburnum is essential for the transport of nutrients in the tree.
Alburnum is derived from Latin 'alburnus' (meaning a type of fish, specifically the bleak), which is related to 'albus' (meaning white). The term refers to the light-colored flesh of the fish.
Think of the Latin word 'albus' meaning white, which helps you remember that 'alburnum' refers to a fish with light-colored flesh.
