- Bryophyte β Sex organ are multicellular & sterile jacket
- Antheridia is protected by perichaetial leaves which surround them & by multicellular hair like structure - paraphyseo.
- Androcytes βΎ motile male gamete βΎ anthrezoids βΎ nucleus + 2cilia (anterior)
- Archegoria β Stalked, multicellular flask shape female sex organ β upper neck & lower venter plant surface lack cuticle β no check of water loss.
- Retention of zygote within female sex organ to nourish developing embryo, appreciably increment chances of survival & growth of zygote
- Riccia β foot & seta absent in sphagnum β seta is indistinguishable.
- Foot β help absorb food for developing sporophyte.

- Riccia β Dichotomously branched, rosetle shaped antheridia & archegonia Lie sunken in longifudinal groove on upper fide of thallus.
- Archerzoid β biflagellate, pear shaped.
- Archegonia β flask Shaped, Feaneck cancel cells, uninucleate egg as mature muclige dissolves.
- Sporophyte β no stalk, reduced & emnedded in thallus.
