The prothallus is haploid, since it grew from a spore which had been formed by meiosis. It does not have any vascular tissue and uses small rhizoids to anchor it to the ground. On the underside of the prothallus the sex organs form. The female structure, called an archegonium, contains a single egg.An antheridium is a haploid structure or organ producing and containing male gametes. The plural form is antheridia, and a structure containing one or more antheridia is called an androecium.

In pteridophytes the sporophyte produces spores through meiosis. The spores are produced by the sporangia in the spore mother cells. These spores germinate to give rise to gametophytes. The gametophytes bear male and female sex organs. Water is required for transfer of antherozoids - the male gametes released from the male sex organ to the mouth of female sex organ. Fusion of male gamete with the egg result in the formation of zygote. Zygote thereafter produces a multicellular well-differentiated sporophyte. In majority of the pteridophytes all the spores are of similar kinds. However, some genera also produce two kinds of spores, macro (larg e) and micro (small) spores. The megaspores and microspores germinate and give rise to female and male gametophytes, respectively. In these plants, the female gametophytes are retained on the parent sporophytes for variable periods. The development of the zygotes develop into young embryos within the female gametophytes. This event is a precursor to the seed habit considered an important step in evolution. Q. In pteridophytes the male and female sex organ of the gametophytes are called ________, respectively.

In Pteridium the archegonia are present

Gametophyte is a dominant phase in the life cycle of a bryophyte. It is more conspicuous, long living, independent, green and freely branched whereas, the sporophytic phase is short lived and dependent upon the gametophyte. The main plant body is haploid and bears sex organs i.e., antheridium and archegonium. Antheridium produces a large number of flagellated male gametes called antherozoids and archegonium is flask shaped with tubular neck and swollen venter. The gametophytic plant body of bryophytes is thalloid in liverworts whereas foliose in mosses. In liverworts, the thallus is differentiated into a dorsal photosynthetic and ventral storage region. In mosses, the gametophyte has two growth stages- protonema stage and leafy stage or gametophore.Q. Bryophytes require water in their habitat for
