Quizplus · Accepted Answer

The description of long, spindle-shaped cells with open pits between them matches that of tracheids, which are found in xylem tissue. Gymnosperms have both tracheids and vessel elements in their xylem, but vessel elements have perforations at their ends, not open pits between cells. Sieve tube elements are found in phloem tissue, not xylem, and have a different shape than tracheids or vessel elements.
