Arrange the given groups of plants in correct evolutionary sequence.
A. Seed ferns
B. Gymnosperms
C. Psilophyton
D. Rhynia-type plants
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → D, C, A, B
D. Rhynia-type plants — first. These were simple, early vascular land plants of the Silurian period.
C. Psilophyton — second. Psilophyton comes just above the Rhynia-type plants in the chart. Many later plant groups branch off from this point.
A. Seed ferns — third. Seed ferns arose from the progymnosperms and flourished in the Carboniferous period.
B. Gymnosperms — last. Gymnosperm groups such as the cycads branch off from the seed-fern line and spread in the later periods.
In the chart below, the groups appear from the bottom (older) to the top (newer) in this order.
