Question

Which is present in vascular bundles of gymnosperms?

• A. Tracheids
• B. Vessels
• C. Companion cells
• D. All of the above

Answer 1

The correct option is A Tracheids

Vessels are limited in growth, and are joined end to end to form continuous tubular structures with perforations in their cross walls. Water and minerals are efficiently conducted through these perforations. Vessels are present in most of the angiosperms. Tracheids are elongated and non-perforated. They have only pit pairs, at the regions of union with other tracheids. Conduction of water and minerals is not as efficient as in vessels. Tracheids are found in most of the gymnosperms.

Vessels and companion cells are absent in Gymnosperms.
Thus, the correct answer is option A.
