Solution
The correct option is D Bordered pits
Tracheids are elongated and non-perforated. They only have 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 pteridophytes and most of the gymnosperms. Vessels 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.
Thus, the correct answer is option B.
