Gymnosperms (meaning "naked seeds") are seed-bearing plants that don't produce flowers, instead they have male and female reproductive organs mostly in the form of cones. Their microsporophylls release pollen into the air to make available to the ovule, in the megasporophylls causing fertilization. Their seeds develop without a protective covering of ovary wall. Conifers (like pines, redwoods, and fir), gingkos, seed ferns, cycadeoids, and cycads are gymnosperms.
Hope this is helpful!
Angiosperms and gymnosperms are two groups of plants that produce seeds. Angiosperms, also known as flowering plants, have seeds enclosed within a fruit. Gymnosperms, such as conifers and cycads, have seeds that are not enclosed within a fruit.
The first organisms that did not require water for reproduction were likely plants and some types of fungi. These organisms evolved mechanisms such as pollen and spores to reproduce in dry conditions without the need for water.
Gymnosperms spread their seeds through various methods such as wind dispersal, animal dispersal, and water dispersal. For example, conifers produce lightweight seeds with wings that are dispersed by the wind, while some gymnosperms rely on animals to eat and then disperse their seeds.
In angiosperm seeds are enclosed inside the ovary whereas in gymnosperm seeds are naked (i. e. born on megasporophyll) Gymnosperms have archegonium for egg whereas in angiosperms it is replaced by an embryo sac.
Gymnosperms had the advantage of producing seeds that were protected within cones, providing them with a greater ability to disperse and survive in various environments. This adaptation allowed them to better compete for resources and reproduce more successfully than primitive plant types that relied on spores for reproduction.

Alternation of generations is the same in all plants in the sense that during sexual reproduction gametophytic generation alters with the sporophytic generation. In angiosperms and gymnosperms the only difference is the presence of embryo sac in the ovule in place of archegonium in gymnosperms. Also double fertilization takes place in angiosperms to have sporophytic endosperm, which remains gametophytic in gymnosperms.
Reproduction in plants take place in flowers or mega- & microsprophylls.

Because they are better adapted for reproduction and dispersal of their seeds.

Gymnosperms were the first plants to reproduce using seeds, a significant evolutionary advancement over spore-based reproduction seen in earlier plants. They typically have exposed seeds on cones, allowing for more efficient reproduction and dispersal. This adaptation enabled gymnosperms to thrive in various environments and contributed to their success during the Mesozoic era. Examples of gymnosperms include conifers, cycads, and ginkgoes.
It occurs in a sexual reproduction. I hope this answers your question!!
