phyla are said to have the gametophyte generation as the "dominant" generation. Phylum Pterophyta (or Pteridophyta or Filicinophyta) -- ferns or " true ferns"

The dominant generation in pteridophytes is

Show Answer. Answer:3 Alternation of Generations For sexually reproducing multicellular organisms In contrast, in flowering plants (angiosperms), the sporophyte is the dominant form. Meiosis; Pollination and Fertilization; Pteridophytes; Reproduction i All gametophyte forms of bryophytes, pteridophytes, and gymnosperms produce The gametophyte is the dominant generation; Nonvascular: grow close to An alternation of generations defines the haploid-diploid, or 1n-2n, life cycle. This occurs in pteridophytes, or ferns, although the SPT stage of pteridophytes is is when the SPT is dominant over GPT, as is the case with all vasc C), Plants have an alternation of generations life cycle.

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. generation is the dominant In Pteridophytes the generation. 11.3 The adult fern plant represents the generation. 11.4 develop from the rhizome, anchor the plant in the soil and absorb water and mineral salts. and therefore produces spores over 11.5 The sporophyte is many generations.

In terms of chromosomes, the gametophyte is haploid (has a single set of chromosomes), and the sporophyte is diploid (has a double set).

Tetrasporic individuals therefore are more dominant and common than sexual individuals. Another important cause of this domination is the fact that tetrasporic

Answer: (c) 4. Prothallus represents (a) sporophytic phase in a fern (b) gametophytic phase in a fern In pteridophytes, dominant free living generation is diploid sporophytic generation. Sporophyte is differentiated into true roots, stem and leaves. Gametophyte develops from spores and is a short lived generation.

In pteridophytes the dominant generation is

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.

It is absent in gymnosperms.

The reproductive structures of the sporophyte (cones in gymnosperms and flowers in angiosperms), produce two different kinds of haploid spores: microspores (male) and megaspores

Life Cycle of Pteridophytes. The life cycle of a Pteridophyte comprises of two distinct phases or generations, each of which produces the other. One phase or generation, the sporophyte, is diploid (2n) and the dominant part of the life cycle. It is the part of the life cycle in which vascular tissue is developed.
