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.
In the alternation of generations life cycle spores grow into gametophyte plants via a process called mitosis. This can be found by looking at a diagram of the alternation of generations.
alternation of generations
Ferns.
In most plants, the sporophyte generation is dominant. In fern, for example, the fern itself is the sporophyte. This organism produces spores that fall to the substrate below and grow into a separate organism called a gametophyte. The gametophyte produces sperm and eggs in order to produce a new sporophyte which grows out of the gametophyte's body, destroying it. It is important to note that the gametophyte is haploid and the sporophyte is dploid.
diploid sporophyte and a haploid gametophyte
The Sporophyte is the dominant generation of the club moss, which is a Lycopodium. Also, club mosses are vascular plants, and the diploid generation is dominant for vascular plants.
The gametophyte has become smaller, and the sporophyte has become larger. To begin with main plant body was gametophytic and sporophyte was dependent on it. Later on, as the evolution progressed, both gametophyte and sporophyte became independent and ultimatly gametophyte became dependent on sporophyte.
The gametophyte of moss is the dominant structure

The sporophyte generation is dominant in ferns.
spore producing plant generation. The dominant generation in pteridophytes and higher plants and alternates with the gametophyte generation.
diploid sporophyte and a haploid gametophyte
sporophyte and gametophye. since plants have alternation of generation, both are multicellular (haploid and diploid)
i swear i hate this question

Plants have what is called an alternation of generations in their life cycle. The two stages are called the sporophyte generation and the gametophyte generation. The sporophyte generation is diploid (has pairs of chromosomes). It produces spores by meiosis (reduction division), so the spores are haploid (contain only one chromosome from each pair). The spores divide by mitosis to produce a multicellular, haploid gametophyte generation. The gametophyte produces gametes (by mitosis) which fuse during fertilization to form a diploid zygote. This then develops into the sporophyte, completing the life cycle. The plants which we call mosses and ferns are the gametophyte generations. However conifers and flowering plants are the sporophyte generation of their life cycle. This is much easier to understand if you see a diagram.
