It is abundant in tropics, with a wide range in growth habits and habitats. Many species are flat creepers (Fig. 8.1 A) on the ground (S. kraussiana). […]

The production of two kinds of spores differing in structure and function, the smaller one producing the male gametophyte and larger one producing the female gametophyte, is termed heterospory. For the first time distinct heterospory (structural as well as functional) is evident in pteridophytes; but out of several hundred forms in the group, only 9 […]

In this article we will discuss about the asexual and sexual modes of reproduction in anthoceros with the help of diagrams. Asexual Reproduction in Anthoceros: By progressive death and decay of older parts of thallus vegetative reproduction is not so common in Anthoceros as in other liverworts, Instead the thallus is capable of producing many […]
