* Hepaticae
* Anthocerotae
* Musci
HEPATICAE -
They are lower forms of bryophytes. They have an undifferentiated thallus.
Sporophytes is very simple and short lived. In some forms sporophyta is differntiated into food, seta and capsule
Eg. Riccia
ANTHOCEROTAE -
Gamerophytes is undifferentiated thallus. Rhizoids are unicelluar and unbranched. Protonemal stage is absent. Sporophyta is differentiated into foot and capsule and no seta.
Eg. Anthoceros
MUSCI -
They have a more differentiated structure than hepaticae. They are highest form of gametophyte. Rhizoids are multi-crllular and branched. Protonemal stage is present. Sporophyte is differentiated into foot, seta and capsule
