Question

Identify the plants that are dominant during the Jurassic period.
a. Monocotyledons and arborescent lycopods
b. Angiosperms and bryophytes
c. Ferns, conifers and cycads
d. Sphenopsida and ginkgos

Answer 1

Hint: Jurassic duration was around fifty-six million ago. In this period flowers with described roots and vascular tissues have been at bloom. In this period, a brand new reproduction approach in the vegetation became evolved. Spore replica was famous for that point and the vascular system changed into used most effective for the motion of water and nutrients at some point of the plant frame.

Complete answer:
• The arid, continental conditions feature of the Triassic step by step eased throughout the Jurassic period, mainly at higher latitudes; the warm, humid weather allowed lush jungles to cowl tons of the panorama.
• Gymnosperms have been surprisingly diverse all through the Jurassic duration. The Conifers, especially, ruled the plant life, as throughout the Triassic; they have been the most various organization and constituted most of the people of massive trees.
• Extant conifer families that flourished throughout the Jurassic blanketed the Araucariaceae, Cephalotaxaceae, Pinaceae, Podocarpaceae, Taxaceae and Taxodiaceae.
• The extinct Mesozoic conifer own family Cheirolepidiaceae ruled low range vegetation
• Cycads, much like bushes, have been also commonplace, as have been ginkgos and Dicksoniaceous tree ferns within the wooded area
• Smaller ferns were possibly the dominant undergrowth, Ginkgo flora had been especially not unusual within the mid- to excessive northern latitudes] In the Southern Hemisphere, podocarps have been specially a hit, even as Ginkgos and Czekanowskiales were rare species

Hence, the correct answer is option (C).

Note: The beginning of the length has become marked by means of the most important Triassic–Jurassic extinction event. Two different extinction activities occurred throughout the duration: the Pliensbachian-Toarcian extinction inside the Early Jurassic and the Tithonian event at the end. In the oceans, present-day coralline algae appeared for the first time, but they had been part of some other fundamental extinction that took place inside the next primary time period.
