NEET BIOLOGY

Detailed explanation-1: -Plants, algae, and some protists hav e a life cycle that alternates between diploid and haploid phases, known as alternation of generations. In plants, the life cycle alternates between the diploid sporophyte and haploid gametophyte.

Detailed explanation-2: -Alternation of generations which is also known as metagenesis is the type of life cycle that occurs in those plants and algae in the Archaeplastida and the Heterokontophyta so as to have diverse haploid sexual and diploid asexual stages.

Detailed explanation-3: -Alternation of generations is a type of life cycle found in terrestrial plants and some algae in which subsequent generations of individuals alternate between haploid and diploid organisms. This can be contrasted to sexual reproduction in animals, in which both haploid and diploid cells are found in every generation.

Detailed explanation-4: -Heteromorphic alternation of generation means when there is a haploid gametophyte in one generation and a diploid sporophyte in another generation. Both the generations are different from each other, morphologically and genetically.
