Alternation of generation” term employed by Hofmeister in 1851. He observed that in mosses and ferns there are two types of morphologically distinct individuals present in the life cycle. Both alternate during a life cycle back to back. Sporophyte generation is main and dominant in pteridophytes.

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? Homosporous Pteridophytes vs Heterosporous Pteridophytes Homosporous pteridophytes are the

Favorite Answer. 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. photosynthetic and independent, whereas sporophytic phase is represented by the zygote. Pteridophytes Pteridophytes include fern plants. Gymnosperms Gymnosperms are seed-bearing plants and include cycads and conifers.

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. - Sporophyte is the dominant generation. - Sporophyte is the green fern plant, is larger and longer-lived phase of life cycle.

Here, the dominant sporophyte produces spores through meiosis.

The dominant generation of a moss is the gametophyte whereas the fern sporophyte generation is dominant; Mosses have separate male and female plants gametophytes, ferns are homosporous with monoecious prothallus; Bryophytes have rhizoids while pteridophytes have hyphae; Ferns can grow bigger and can grow in less damp areas

They show heteromorphic alternation of generations and dominant generation is the sporophytic generation. 6.
