What are the two types of seedless plants?

The two main types of seedless plants are bryophytes and pteridophytes. Bryophytes, which include mosses, liverworts, and hornworts, are non-vascular plants that typically grow in moist environments. Pteridophytes, such as ferns and horsetails, are vascular plants that reproduce via spores and can often thrive in a variety of habitats. Both groups rely on water for reproduction and do not produce seeds.
