HORTICULTURE

Detailed explanation-1: -Plants alternate between the diploid sporophyte and haploid gametophyte, and between asexual and sexual reproduction. Therefore, the life cycle of plants is known as alternation of generations. The ability of the plants to reproduce sexually and asexually helps them to adapt to different environments.

Detailed explanation-2: -All plants transition between a haploid (n) gametophyte and a diploid (2n) sporophyte in the alternation of generation life cycle. Depending on the species, sometimes one or the other is the dominant stage. Bryophytes are a group of simple non-vascular plants that include mosses, liverworts, and hornworts.

Detailed explanation-3: -All plants alternate generations. There is an evolutionary trend from sporophytes that are nutritionally dependent on autotrophic (self-feeding) gametophytes to the opposite‐gametophytes that are dependent on autotrophic sporophytes.

Detailed explanation-4: -Alternation of generations This life cycle is found in some algae and all plants. Species with alternation of generations have both haploid and diploid multicellular stages. The haploid multicellular plants (or algae) are called gametophytes, because they make gametes using specialized cells.

Detailed explanation-5: -alternation of generations, also called metagenesis or heterogenesis, in biology, the alternation of a sexual phase and an asexual phase in the life cycle of an organism. The two phases, or generations, are often morphologically, and sometimes chromosomally, distinct.
