Question

Find the CORRECT chronological order of appearance of angiosperms
(i) Chlorophyte ancestors
(ii) Tracheophyte ancestors
(iii) Psilophyton
(iv) Rhynia type plants
(v) Seed ferns
(vi) Progymnosperms

• A. $i, \, ii, \, iii, \, iv, \, v, \, vi$
• B. $i, \, ii, \, iv, \, iii, \, v, \, vi$
• C. $i, \, ii, \, iv, \, iii, \, vi, \, v$
• D. $i, \, ii, \, iii, \, iv, \, vi, \, v$

Answer 1

Answer: (C)

The chlorophyte ancestors are the green algae which have given rise to all the green plants. The tracheophytes have originated from the green algae followed by the Rhynia type plants which are a genus of Devonian vascular plants with the subdivision of psilophyton. The progymnosperms are found to form a link between the psilophytons and the gymnosperms. The pteridospermatopsida or the seed ferns belong to a group of extinct seed-bearing plants.
