Question

What is the term for plants that lack vascular tissues, roots, leaves, seeds, and flowers?

Answer 1

bryophytes

Modern nonvascular plants are called bryophytes. There are about 17,000 bryophyte species. They include liverworts, hornworts, and mosses. Mosses are the most numerous group of bryophytes. You can see an example of moss in Figure below . Like the moss in the figure, most bryophytes are small. They lack not only vascular tissues. They also lack true roots, leaves, seeds, and flowers. Bryophytes live in moist habitats. Without the adaptations of vascular plants, bryophytes are not very good at absorbing water. They also need water to reproduce.
