Seed plants:produce seeds
Seedless plants:don't produce seeds
Meiosis in seedless plants produces spores, which are haploid reproductive cells that can grow into multicellular haploid organisms called gametophytes. These gametophytes eventually produce gametes for sexual reproduction.
In a moss, gametophytes are photosynthestic.
Male and Female gametophytes are in separate plants
Seed plants are flowering plants so they product pollen that land on the female ovule and then produce a pollen tube that releases 2 sperm to fertilize the ovum and the polar nuclei and these form into a seed. In other seedless plants like algae and mosses the plants produce spores which are similar to pollen and many different versions of female gametes. To be honest seedless plants have many different life cycles that are much more in depth so the fertilization process and the maturation of the plants are very different.
No, gametophytes of seed plants are usually very small and dependent on the sporophyte for nutrients. They are reduced in size compared to the sporophyte generation.

No. there melons. they also call em ground squash. gametophytes are plants that are like, for example moss.
gametophytes
Gametophytes go through mitosis to create gametes (pollen in male gametophyte and egg in female gametophyte)
egg

this is bull i type the question and sometimes it shows mup but most of the time it doesnt :(
antheridium
Only in those cases where spores are not differentiated into micro- & megaspores for developing the gametophytes. Thus homosporous vascular plants produce archegonia and antheridia on same gametophyte.
