| (C) Jurassic | (III) Seed ferns |
| (D) Cretaceous | (IV) Progymnosperms |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A) - (IV), (B) - (III), (C) - (II), (D) - (I)
(A) Devonian — this matches (IV) Progymnosperms. In the book’s chart of plant evolution, progymnosperms arise in the Devonian, from the Psilophyton line.
(B) Carboniferous — this matches (III) Seed ferns. Seed ferns grow out of the progymnosperms in the Carboniferous, the period of the great coal-forming forests.
(C) Jurassic — this matches (II) Cycads. The chart places cycads in the Jurassic of the Mesozoic era.
(D) Cretaceous — this matches (I) Gnetales. Gnetales appear in the Cretaceous on the chart, near the time the flowering plants spread.
