Question

Which of the following plant structures is responsible for the evolution of 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 vascular tissue led to the evolution of first vascular seedless plants (club mosses and ferns). Some of these ferns were long trees and occupied earth as dense forest as the presence of vascular tissues enables these plants to conduct water+ mineral and food to different plant parts. Seed-bearing and flowering plants appeared later during evolution. Deciduous leaves are the adaptation to withstand extreme winters by mesophytes. Thus, the correct answer is D.
