What are seedless nonvascular plants?
Plants that lack vascular tissue, which is formed of specialized cells for the transport of water and nutrients, are referred to as non-vascular plants. Liverworts, mosses, and hornworts are seedless, non-vascular plants that likely appeared early in land plant evolution.
Which plant is nonvascular?
Nonvascular plants are called bryophytes. Nonvascular plants include liverworts, hornworts, and mosses. They lack roots, stems, and leaves.
What are 2 types of non-vascular plants?
Non-vascular plants include two distantly related groups:
- Bryophytes, an informal group that taxonomists now treat as three separate land-plant Divisions, namely: Bryophyta (mosses), Marchantiophyta (liverworts), and Anthocerotophyta (hornworts).
- Algae – especially the green algae.
