The sporophyte 2n is paired and they produce spores by meiosis, and the gametophytes nn are not paired and produce gametes by mitosis.

gametophyte: The gamete-bearing individual or phase in the life cycle of a plant having alternation of generations sporophyte: The spore-producing individual or phase in the life cycle of a plant having alternation of generations
Plants have two stages in their life cycle, sporophyte stage and the gametophyte stage.
Alternation of generations is used to describe a plant life cycle.
The gametophyte and the sporophyte stages of a plant alternate to complete the life cycle.
Gen 1 = The plant reproduces sexually Gen 2 = The offspring of that plant reproduce asexually and the cycle begins again, hence the name alternation ---Caveat--- This is a very simple explanation and surely there are exceptions and important details to consider depending on the exact species. For instance, triggers that can cause an alternation of generations, or sequences *how many times a the plant reproduces sexually/asexually before switching. Plant reproduction can be very complex! Good question. Just remember, all true plants will have alternating 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.

the osmosis stage and the diffusion stage The above is false. The correct answer is the haploid stage and the diploid stage.
A mature sporophyte produces the spores. Likewise a mature gametophyte produces the gametes. The life cycle of the plant is completed by the alternation of these two generations.
a life cycle of a plant is like the growth of the plant in different seasons and how fast it grows
It is an advantage for some plants to alternate generations because, by alternated generations the plant can stop any harmful traits from passing onto future generations.
Any plant or animal that depended on the disappearing one for part of its life cycle will move closer to endangerment, until it finds a new ecological niche. If the extinct plant or animal was essential for some part of the life cycle then a second species is likely also go extinct, as not enough individuals are likely to adapt in the space of a few generations.
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.
