Question

Arrange the following plants in the ascending order of evolution.
Cycads, monocotyledons, dicotyledons, progymnosperms, seed ferns, psilophyton.

• A. Psilophyton, seed ferns, progymnosperms, cycads, dicotyledons, monocotyledons
• B. Psilophyton, progymnosperms, seed ferns, cycads, dicotyledons, monocotyledons
• C. Psilophyton, progymnosperms, seed ferns, cycads, monocotyledons, dicotyledons
• D. Progymnosperms, psilophyton, seed ferns, cycads, dicotyledons, monocotyledons

Answer 1

Answer: (B)

Psilophyton (genus of extinct vascular plants) ⟶ progymnosperms (extinct group of plants that flourished in the mid to late Devonian (360-350 MYA) and contained the ancestors of modern gymnosperms) ⟶ seed ferns (pteridospermatophyta are several distinct groups of extinct seed plants) ⟶ cycads (plants typically characterized by a stout and woody trunk with a crown of large, hard and stiff, evergreen leaves) ⟶ Dicotyledons (embryo with two cotyledons) ⟶ monocotyledons (embryo with one cotyledon).
