Final answer:
Liverworts, known as Marchantiophyta, are bryophytes with leaf-like growths and are closely related to the earliest terrestrial plants.
Step-by-step explanation:
The bryophytes called liverworts, or Marchantiophyta, have leaf-like structures that grow on a stalk. Liverworts are one of the three divisions of bryophytes, alongside hornworts and mosses, and are thought to be the plants most closely related to the first land plants. Liverworts have diversified into more than 6,000 species, and some exhibit lobate green structures that resemble the lobes of a liver, hence their name. These gametophytes are a significant part of the bryophyte's life cycle, performing photosynthesis and enabling the plant to thrive in various habitats, from damp regions to deserts.
