There is alternation of generation in the lifespan of pteridophytes. This is known as metagenesis. Just like in the seed bearing plants and mosses there is a diploid generation alternating with a haploid generation. The diploid generation is the sporophyte which produces the spores.

Ferns and other pteridophytes are seedless vascular plants. pages 427-430 In contrast to mosses, the sporophyte is the dominant fern generation (Figure

The life cycle of the fern differs from both higher plants (Gymnosperm, Angiosperm) and Bryophytes. In bryophytes the gametophytic generation is the dominant phase in the life cycle and the sporophyte phase is dependent upon it whereas in angiosperms, the sporophyte is the dominant phase and the gametophyte is dependent upon it. 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?

Here, the dominant sporophyte produces spores through meiosis. The gametophyte generation forms gametes by mitosis.

Pteridophytes show a true alternation of generations. Here, the dominant sporophyte produces spores through meiosis. The gametophyte generation forms gametes by mitosis. The spores are produced by the sporangia in the spore mother cells.

Pteridophytes, also known as generally the dominant phase. In seed plants, the phyte generation is reduced to just a few cells in the germinating pollen grains andtheovules. Occurrence and evolution of Pteridophytes with its origin and economic importance in Pteridophyta is a group of ancient plants. They formed the dominant part of the earths during Palaeozoic and Mesozoic periods on soral evolution.

Sporophyte generation is main and dominant in pteridophytes.Strasburger (1894) discovered the process meiosis, the actual phenomenon responsible for bringing about alternation of generation. The reduction in the number of chromosomes leads to the formation of a new individual in life cycle.

•In pteridophytes, gymnosperms, and angiosperms, the sporophyte is the dominant generation.

In which of the following groups would you place a plant that produces spores, lacks seeds and has … Which is the dominant phase in pteridophytes? - 11841271 vaibhavkhule55 vaibhavkhule55 16.08.2019 Biology Secondary School answered Which is the dominant phase in pteridophytes? 2 See 2019-01-04 Pteridophytes show a true alternation of generations.

Alternation of the haploid gametophytic phase (n) with diploid sporophytic phase (2n) during the life cycle is called alternation of generation. Following type of life cycles are found in plants: (a) Haplontic life cycle: Gametophytic phase is dominant.

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.

The gametophytic phase of the life gametophyte is dominant in bryophytes whereas the sporophyte is dominant in pteridophytes. Both dominant. generations are autotrophs. The main difference (b) In gymnosperms female gametophyte is free-living (c) Antheridiophores and archegoniophores are present in pteridophytes (d) Origin of seed habit can be Sporophyte is dominant generation and can grow independent of gametophyte ( no more ģdeadbeat sporophytesē!)
