Detailed explanation-1: -Evolution of Nonvascular Plants The first nonvascular plants to evolve were the liverworts. The hornworts evolved somewhat later, and mosses apparently evolved last. Of all the bryophytes, mosses are most similar to vascular plants.
Detailed explanation-2: -Gymnosperms were the first seed plants to have evolved. The earliest seedlike bodies are found in rocks of the Upper Devonian Series (about 382.7 million to 358.9 million years ago).
Detailed explanation-3: -Nonvascular plants were the first plants to evolve. Compared to other plants, their small size and lack of specialized structures, such as vascular tissue, stems, leaves, or flowers, explains why these plants evolved first.
Detailed explanation-4: -Seedless Vascular Plants. By the Late Devonian period (385 million years ago), plants had evolved vascular tissue, well-defined leaves, and root systems. With these advantages, plants increased in height and size.
