Bryophytes (mosses, liverworts and hornworts) have a dominant gametophyte phase on which the adult sporophyte is dependent for nutrition.The embryo sporophyte develops by cell division of the zygote within the female sex organ or archegonium, and in its early development is therefore nurtured by the gametophyte.

Characteristics of Bryophytes There are several characteristic features of bryophytes. First, the green tissue that makes up most of the plant body is not vascularized; it does not have xylem and phloem cells.

At regular intervals depending on species and weather condition, mosses produce small sexual structures known as archegonium (female structure that produces egg cells), or antheridium (male structure that produces sperm cells).
