Identify the incorrect statement.
A
Sapwood is involved in conduction of water and minerals from root to leaf.
B
Sapwood is the innermost secondary xylem and is lighter in colour.
C
Due to deposition of tannins, resins, oils etc., heart wood is dark in colour.
D
Heart wood does not conduct water but gives mechanical support.
Detailed Solution
Sapwood is the outermost (peripheral), lighter coloured region of secondary xylem that conducts water and minerals.
The innermost secondary xylem is the dark coloured heartwood (due to deposition of tannins, resins, oils etc.), which gives mechanical support.
So 'sapwood is the innermost secondary xylem' is incorrect.
