The conspicuous part of a fern plant is a _____. diploid sporophyte. In contrast to bryophytes, in vascular plants the dominant stage of the life cycle is the _____. sporophyte. What evolutionary development allowed plants to grow tall?These spores develop into two distinct types of gametophytes; one type produces sperm and the other produces eggs. The male gametophyte develops reproductive organs called antheridia (produce sperm) and the female gametophyte develops archegonia (produce eggs). Why Sporophyte is dominant over Gametophyte?

Which organ produces the Spermatozoids in Ferns?

The egg-producing organ, the archegonium, incorporates one gamete (intercourse mobile), which is always situated in the lower, kind of dilated portion of the archegonium, the venter. The higher a part of the archegonium, the neck, consists of 4 rows of cells containing central neck cells.
