CLASS ANTHEROCEROTAE or HORNWORTS
Members of this clas resemble liverworts but may not be closely related to them.
Hornworts have a single disc-shaped chloroplast in each cell like many algae.
Antheridia and archegonia are embedded in the thallus, and the sporophyte which develops after fetilizationforms a "horn".
Meiosis
occurs within sporngia and spores are formed.
