Characteristics of the Division Bryophyta Characteristics of the Division Bryophyta Photosynthetic, non-vascular plants in which the female sex organ is the archegonium.
All groups show clear alternation of generations.
The gametophyte generation is dominant, conspicuous and independent. The ovum remains in the archegonium and spermatozoids swim to it by chemotaxis. Spores dispersed by a mechanism which ensures dispersal in dry weather only. No vascular tissue in either generation. Root-like structures are rhizoids.
