Liverworts have lobed or dichotomously branched thallus, which is dorsoventrally flattened. The sperm must swim from the antheridium to the archegonium to fertilize the egg, meaning the fern depends on water for fertilization. En contraste con los estomas, estas cmaras de aire siempre tienen los poros abiertos y estos no se pueden cerrar. Like MOSSES, liverworts have alternation of generations between haploid gamete-bearing forms (gametophytes) and diploid spore-bearing forms (sporophytes).

With these they absorb water directly from the environment itself and move it through its structure. Problemes - 3 eoiet. The haploid gametophyte generation is characterized by the production of male and female gametes through mitosis. En los gametofitos, segn su naturaleza, se desarrollan estructuras de reproduccin sexual sostenidas por un largo filamento cuyo extremo produce una forma similar a un paraguas (en el caso de arquegonios), o una forma de almohadilla aplanada o lente (en el caso de anteridios).
