Talk about steps of bryophytes sexual reproduction

Gametophytes can form multiple gametangia, each of which produces gametes. Male gametophytes develop reproductive structures called antheridia (flagellated, motile) that produce sperm cells by mitosis. Female gametophytes develop archegonia (sing. archegonium) that produce eggs by mitosis. Each archegonium produces one egg, whereas each antheridium produces many flagellated sperm. Some bryophytes bear antheridia and archegonia within the same gametophyte. Fertilization occurs in the presence of water. The type of reproduction is oogamy.
