Practice question

The right choice is C: Shorter and wider than tracheids. In PSS- Sec-F-Transport, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) Narrower than tracheids; B) Absent in angiosperms; D) Present only in gymnosperms. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.
