Question

Gymnosperms are soft-wooded as they lack

• A. Cambium
• B. Phloem fibres
• C. Thick-walled tracheids
• D. Xylem vessels

Answer 1

The correct option is D Xylem vessels

In coniferous gymnosperms, secondary growth takes place by the formation of vascular cambium. it produces secondary xylem or wood towards its innerside and secondary phloem or bast towards outerside. Secondary xylem, shows more number of vessels without pores. So these are called non-porous vessesl. So the wood is called soft wood or non-porous wood.

So, the correct option is 'xylem vessel'.
