The most primitive of these, the liverworts, have flat bodies sometimes only one cell thick and belong to one of its three sub-divisions, the hepatophyta; the other two being anthocerophyta and mosses.
These have biflagellate sperm, so monoicous members are especially self- fertile in the presence of water. A flapping membrane called an operculum protects their minor generation and, though they exhibit normal alternation of generations, members of this paraphyletic division are haploid-dominated.
