Question

Which of the following plant structures evolved for the first terrestrial forests?

• A. Flowers
• B. Naked seeds
• C. Covered seeds
• D. Vascular tissue
• E. Deciduous leaves

Answer 1

The correct option is D Vascular tissue

Evolution of dominant sporophyte and vascular tissue led to the evolution of first vascular seedless plants (club mosses and ferns) that arose and diversified during the Silurian and Devonian periods of the Paleozoic era. Some of these ferns were long trees and occupied earth as dense forest as a presence of vascular tissues enables these plants to conduct water+ mineral and food to different plant parts. Spermatophytes (angiosperms and gymnosperms) appeared later during evolution. Thus, the correct answer is D.
