Answer -
Bryophytes, Pteridophytes, and Gymnosperms are the plants that bear archegonia.
The life cycle of Bryophytes
(i) Bryophytes are haploid, and they produce gametes. The sexual organs in bryophytes are multicellular.
(ii) The male sex organ is the antheridium, which produces biflagellate anterozoids. Female sexual organs are called archegonium, which produces a single egg.
(iii) Antheridium releases anthrozoids into the water that come into contact with the archegonium.
(iv) An antherozoid fuses with the egg to produce the zygote.
(v) The zygote undergoes reduction division to produce a multicellular body called a sporophyte.
(vi) Saprophytes undergo reduction division to produce haploid spores.
(vii) These spores germinate to produce gametophyte.
