The dominant generation in pteridophytes is

Following type of life cycles are found in plants: (a) Haplontic life cycle: Gametophytic phase is dominant. photosynthetic and independent, whereas sporophytic phase is represented by the zygote. The plant body or the vegetative phase is diploid in pteridophytes, gymnosperms and angiosperms. The reproductive structures like the stobili in pteridophytes, ovules and microsporangium, anther are also diploid. Here, only the reproductive cells undergo meiosis or gametogenesis to give rise to male and female gametes that are haploid. 2017-05-26 Pteridophytes Pteridophytes include fern plants.

Prothallus represents In Bryophytes, the dominant phase in the life-cycle is the gametophyte, for the sporophyte is retained upon it throughout its life and is either partially or completely dependent on it for nutrition. Contrary to it in pteridophytes the sporophyte is the dominant generation, for it very soon becomes independent of the gametophyte (prothallus) and grows to a much greater size. 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 .

In all other land plants the sporophyte generation is dominant. 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.

Jun 10, 2013 Also like lycophytes, the pteridophytes have a distinct sporophyte and gametophyte generation, with the sporophyte generation the dominant

This represents the first stage of the gametophyte generation. Assertion : In pteridophytes, gametophyte is the dominant phase. Reason : They reproduce by spore production. (a) If both assertion and reason are true and reason is the correct explanation of the assertion. (b) If both assertion and reason are true but reason is … The dominant, photosynthetic phase in such plants is the free-living gametophyte. This kind of life cycle is termed as haplontic. Many algae such as Volvox, Spirogyra and some species of Chlamydomonas represent this pattern (Figure 3.7 a).
