In this article we will discuss about the structure of Anthoceros with the help of diagrams. External Morphology of Anthoceros: The gametophytic plant body is a small greasy dark-brown prostrate, dorsiventral thallus. The thallus is usually dichotomously lobed (e.g. A. fusiformis, Fig.6.29B) or sub-orbicular (e.g. A. crispulus, Fig. 6.29 A). The thallus is often raised on a thick ascending stalk-like [...]
In this article we will discuss about the vegetative and sexual modes of reproduction in Pogonatum. Vegetative Reproduction in Pogonatum: Vegetative propagation of Pogonatum takes place by the following methods: Gemmae: Bud-like gemmae develop on the rope-like rhizoids and each gemma forms a gametophyte after germination. Secondary Protonema: The secondary protonema develops from any part of the plant other than [...]
In this article we will discuss about the evolution of sporophytes and gametophytes in bryophytes. Evolution of Sporophyte in Bryophytes: The sporophyte of bryophytes is called sporogonium which generally consists of a single, terminal sporangium (monosporangiate) with a bulbous foot and with or without an unbranched stalk or seta. The sporogonium is very delicate, short-lived and nutritionally dependent on its [...]
