The Bryophyta group includes structures like thalli and reproductive organs, particularly in the class Hepaticopsida. These plants have simple or foliose body structures with distinct characteristics such as aseptate rhizoids, ventral scales, and chloroplasts without pyrenoids. The gametophyte is st

Marchantia, a thalloid bryophyte, exhibits dichotomous branching and a gametophyte-dominant life cycle. It is dioecious with distinct male and female thalli bearing antheridia and archegonia. With around 65 global species, including common ones like M. polymorpha, it thrives in moist, sandy habitats

The evolution of sporophytes in bryophytes like liverworts and mosses follows two main theories - progressive sterilization and reduction. The progression of sporophytes from simpler forms like Riccia to more complex forms like Sphagnum is discussed, highlighting the stages of development such as th
