Current Question (ID: 12448)

Question:

A piece of wood having no vessels (trachea) must belong to

Options:

1. Teak
2. Mango
3. Pine
4. Palm

Solution:

Pine is a gymnosperm and belongs to the group of softwoods. Gymnosperms, including pines, do not have vessels or tracheids in their xylem, which are the water-conducting cells commonly found in angiosperms (flowering plants). Instead, gymnosperms have tracheids as their primary water-conducting cells in the xylem. Teak (option 1), Mango (option 2), and Palm (option 4) are angiosperms, and they do have vessels or tracheids in their xylem for water conduction. So, they are not the correct answer to this question.
