In this article we will discuss about the life cycle of bryophytes with the help of diagrams. The life cycle of a bryophyte involves an alternation of generations—the gametophyte and sporophyte, which are different in morphology (heteromorphic) and differ in their level of ploidy (heteroploid). The gametophyte or gamete-producing generation is distinct in its morphology […]

in this article we will discuss about the modes of reproduction in psilotum with the help of diagrams. Stout aerial branches bear large conspicuous sporangia (Fig. 7.1 A). Each sporangium is a 3-lobed structure (Fig. 7. 1B, C). It is borne on a forked appendage. It has been described as: (a) Trilocular sporangium (b) Trisporangiate […]

The life cycles of archegoniate plants in general, and of pteridophytes in particular, reveal that two cells -spore and fertilized egg- initiate two separate phases of growth by giving rise to two dissimilar and independent plants. Each plant is characteristic of its generation. While gametophyte and sporophyte, are two dissimilar phases, as well as two […]
