NEET BIOLOGY

Detailed explanation-1: -Alternation of generations is common in plants, algae, and fungi. This can be compared to the sexual reproduction in animals where both haploid and diploid cells are found in every generation. Plants alternate between the diploid sporophyte and haploid gametophyte, and between asexual and sexual reproduction.

Detailed explanation-2: -Yes, the sporophyte generation of plants in phylum Coniferophyta is the dominant generation. These are the large trees and shrubs that we commonly see. The gametophyte generation, the one that is not dominant, is the generation of pollen grains that produce the gametes.

Detailed explanation-3: -Alternation of generations occurs in almost all multicellular red and green algae, both freshwater forms (such as Cladophora) and seaweeds (such as Ulva).

Detailed explanation-4: -The life cycle of a gymnosperm involves alternation of generations, with a dominant sporophyte in which the female gametophyte resides, and reduced gametophytes. All gymnosperms are heterosporous.
