1. Bryophyta (Mosses): This phylum includes mosses, liverworts, and hornworts. They lack vascular tissue (xylem and phloem) for transporting water and nutrients, so they rely on diffusion for these processes. They also don't produce seeds and reproduce using spores.

2. Hepatophyta (Liverworts): Liverworts are a group of nonvascular plants that are closely related to mosses. They have a flattened, lobed structure that resembles a liver, hence their name.

3. Anthocerotophyta (Hornworts): Hornworts are characterized by their long, horn-shaped sporophytes. They are similar to liverworts and mosses in their lack of vascular tissue and reliance on spores for reproduction.
