Why are bryophytes called amphibious plants in plant kingdom?

Explanation

1. **Definition of Bryophytes**: Bryophytes are non-vascular plants that include mosses, liverworts, and hornworts. They are simple plants that do not have true roots, stems, or leaves.

2. **Habitat Requirements**: Bryophytes primarily grow in moist environments. They can be found in soil, on rocks, and in damp areas. However, they do require a certain amount of moisture to thrive.
