Answer:
Gymnosperms
Explanation:
Gymnosperms produce both male and female cones, each making the gametes needed for fertilization; this makes them heterosporous. Megaspores made in cones develop into the female gametophytes inside the ovules of gymnosperms, while pollen grains develop from cones that produce microspores.
Gymnosperms are name of the group of spermatophytes that are cone-bearing plants. The correct option is C.
In contrast to angiosperms, or flowering plants, whose seeds are encapsulated by mature ovaries or fruits, a gymnosperm is any vascular plant that propagates through a bare seed, or ovule.
Many gymnosperm seeds are borne in cones and are not visible until the plant matures.
Gymnosperms are a small class of plants that rarely flower and produce "bare seeds." This means that the seeds are produced on the reproductive structure's surface rather than within it, as in a fruit.
Gymnosperms are a spermatophyte plant group that includes cone-bearing plants.
Thus, the correct option is C.
