Question

The woody structure of the Gymnosperms - Welwitschia, Ephedra and Gnetum closely resemble that of ____________.

• A. Pteridophytes
• B. Monocotyledons
• C. Angiosperms
• D. Dicotyledons

Answer 1

The correct option is D Dicotyledons

The xylem is generally made up of tracheids and vessels and are also present in Gnetum, Ephedra and Welwitschia. Therefore, their wood resembles, that of dicots, as in monocots the vascular bundles are scattered in the ground tissue and are closed for secondary growth. In Pteridophytes the secondary growth is absent and the xylem consists of only tracheids. Dicots and monocots are classes under Angiosperms.

So, the correct answer is 'Dicotyledons'
