Division Bryophyta: The Mosses and Liverworts

The simplest and perhaps most primitive of the land plants are the members of the Division Bryophyta. These plants, commonly known as mosses and liverworts, lack vascular tissue (xylem and phloem) and consequently are usually small in size and restricted to moist habitats. Like all other land plants, the bryophytes exhibit a life cycle with sporic meiosis and an alternation of haploid, gamete-producing and diploid, spore-producing generations. In contrast to the algae, the bryophytes (as well as the other terrestrial plants) have multicellular sex organs.
 

Bryophytes, such as these mosses and liverworts, are small plants that can often be found in moist habitats.
