The process of reproduction for mosses and liverworts is called alternation of generations. This involves the alternation between a haploid gametophyte stage, which produces gametes, and a diploid sporophyte stage, which produces spores. This cycle allows for both sexual and asexual reproduction in these plants.
In the alternation of generations life cycle, fertilization requires two gametes, typically one from a male and one from a female organism. These gametes are often produced through meiosis and can be either motile sperm and non-motile eggs in animals or similar structures in plants. The fusion of these gametes results in the formation of a diploid zygote, which will develop into a sporophyte, leading to the production of spores through meiosis, thus continuing the cycle. This process emphasizes the alternation between haploid and diploid stages in the life cycle of many plants and some algae.
Brown algae show a distinct alternation of generations, characterized by a multicellular sporophyte generation and a multicellular gametophyte generation. The alternation of generations allows for both asexual and sexual reproduction within the life cycle of brown algae.

In the life cycle of an organism that undergoes alternation of generations, there are two alternating phases: a sexual phase where the organism produces gametes (sex cells) and a asexual phase where the organism reproduces without gametes.
The alternation of generations in plants involves a cycle where plants switch between a multicellular diploid phase (sporophyte) and a multicellular haploid phase (gametophyte). This impacts the plant life cycle by allowing for genetic diversity through the production of spores and gametes, and ensures successful reproduction through the fusion of gametes.
Plants exhibit alternation of generations that includes both diploid and haploid multicellular stages.The multicellular diploid stage is called the sporophyte and haploid stage is called gametophyte.

Generations
According to the alternation of generations life cycle when you look at a horsetail plant body you are looking at the sporophytic plant body.
A sporophyte will produce spores. Spores develop into gametophytes which have one sex (They are either male or female). Gametophytes produce gametes (egg/sperm, depending on sex of gametophyte) The gametes fuse together by fertilization producing a zygote. The zygote develops into the sporophyte and the process starts again. - ThatTechnoKid
The male and female gametes unite to form the zygote. Zygote develops into a new sporophyte. This sporophyte after growing vegetatively again enters into the reproductive phase and develops gametes. These gametes again unite to form a new zygote. Thus through alternation of these two generations the life cycle of a plant gets completed.
