In the Pteridophyte division both the sporophyteand gametophytegenerations live as free living plants. The sporophyte is much larger and longer lived than the gametophyte. It is the dominant generation and what we recongnize as ferns, clubmosses, et cetera.
gametophyte is dominant in bryophytes whereas the sporophyte is dominant in pteridophytes.
Tags: Which of the following is a not characteristic of Pteridophytes? The dominant phase in the tracheophyte life cycle is the diploid (sporophyte) stage. The gametophytes are very small and cannot exist independent of the parent plant. The reproductive structures of the sporophyte (cones in gymnosperms and flowers in angiosperms), produce two different kinds of haploid spores: microspores (male) and megaspores
gametophyte is dominant in bryophytes whereas the sporophyte is dominant in pteridophytes. Pteridophytes show a true alternation of generations. Here, the dominant sporophyte produces spores through meiosis. The gametophyte generation forms gametes by mitosis.

4.triploid. Show Answer. Answer:3 Alternation of Generations For sexually reproducing multicellular organisms In contrast, in flowering plants (angiosperms), the sporophyte is the dominant form.
Add your answer and earn points. This means that a diploid generation (the sporophyte, which produces spores) is followed by a haploid generation (the gametophyte or prothallus, which produces gametes). Pteridophytes differ from bryophytes in that the sporophyte is branched and generally much larger and more conspicuous, and from seed plants in that both generations are independent and free-living.

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 . Ferns can be used to illustrate the life cycle stages common to all pteridophytes.
D), Plants are The gametophyte is the dominant generation in a fern plant.
