Which of the following tracheophytes are also called arthrophytes______________?
Correct answer: C. Sphenopsids
- A. Psilopsids
- B. Lycopsids
- C. Sphenopsids
- D. Prteropsids
Explanation
Sphenopsids are called arthrophytes because their jointed, ribbed stems have conspicuous nodes and internodes, as seen in Equisetum. The likely confusion is with lycopsids, which are characterised by small leaves called microphylls rather than jointed stems.
