Question

Choose the correct answers from the alternatives given:
In a transversely cut out trunk of a tree there is an outer lighter region of the secondary wood which is known as

• A. Heartwood
• B. Sapwood
• C. Spring wood
• D. Autumn wood

Answer 1

Answer: (B)

Sapwood

Sapwood, also called alburnum is the outer living layers of the secondary wood of trees, which engage in transport of water and minerals to the top of the tree. The cells, therefore, contain more water and lack the deposits of darkly staining chemical substances commonly found in the heartwood.

Hence, the correct answer is 'Sapwood'.
