Bryophytes include mosses and liverworts. Ferns and horsetails are pteridophytes. The plant body is thallus like and lacks true roots, stem or leaves. It produces gametes, hence is called a gametophyte. In mosses, after
fertilisation, the zygote develops into a sporophyte, consisting of foot, seta and capsule. Asexual reproduction in liverworts takes place by gemmae. Bryophytes are called amphibians of plant kingdom because the plants can live in soil but are dependent on water for sexual reproduction.
