Proposals have been made to divide it among several new kingdoms, such as Protozoa and Chromista in the Cavalier-Smith system. The prominence of the gametophyte in the life cycle is also a shared feature of the three bryophyte lineages extant vascular plants are all sporophyte dominant. The definition was posited because extinct organisms are hardest to classify: Differentiated top and bottom surfaces, two ciliated cell layers, amoeboid fiber cells in between.

Fertilized eggs become zygotes, which develop into sporophyte embryos inside the archegonia. Thus some sources place horsetails in division Arthrophyta and ferns in division Pteridophyta, [18] while others place them both in Pteridophyta, as shown below.

Bryophytes depend on water for reproduction and survival. This page was last edited on 18 Bdyophytaat These terms occasionally may be used instead of “monoicous” and “dioicous” to describe bryophyte gametophytes.

Bryophytes can grow where vascularized plants cannot because they do not depend on roots for an uptake of nutrients from soil. This article is in a list format that may be better presented using prose.

Molecular analysis of Zygomycota has found it to be polyphyletic its members do not share an immediate ancestor[35] which is considered undesirable by many biologists.
