Identify the incorrect statement.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.
