In this article we will discuss about the anatomy of anthoceras with the help of a suitable diagram. The thallus of Anthoceros is several layers thick but it lacks a definite midrib. In a thallus all cells are thin-walled (Fig. 3.2B). On the ventral surface of the thallus are smooth colourless rhizoids. Stomata-like pores occur on the undersurface. On the [...]
In this article we will discuss about the process of reproduction with the help of diagrams. Funaria is monoecious and protandrous. A young plant to begin with produces antheridia at its apex (Fig. 4.1 A) and on a branch appear archegonia. Towards maturity, the branch bearing a developing sporophyte (Fig. 4.1G) tends to dominate and its main stem becomes inconspicuous, [...]
In this article we will discuss about the process of reproduction in sphagnum with the help of diagrams. Sphagnum can be dioecious as well as monoecious; but antheridia occur on different branches. Initially, the sexual branches are in the capitulum but due to elongation of the main stem they are isolated. The antheridial branches (Fig. 4.5B) are specialized divergent branches [...]
