It is customary to place the dominant generation in the top half of the life cycle diagram. The figure given above summarises the life cycle of a typical Bryophyte. Gametophyte lifecycle dominated O nly vascular tissue found in sporophyte stage Heterosporous (Spores each have a gender) Dioecious (sexual organs found on different plants) Manipal 2010: Dominant generation in bryophytes is (A) capsule (B) sporophyte (C) gametophyte (D) seta. Check Answer and Solution for above Biology qu All pteridophytes have a true alternation of generations, in which a dominant sporophyte generation produces spores through meiosis , and a free-living gametophyte generation forms gametes (egg and sperm) by mitosis .

Many algae such as Volvox, Spirogyra and some species of Chlamydomonas represent this pattern (Figure 3.7 a). Both have a dominant sporophytic generation. Both types develop into gametophytes. In both types, the gametophyte obtains the nutrition from the sporophyte. What is the Difference Between Homosporous and Heterosporous Pteridophytes?
