Seed plants:produce seeds Seedless plants:don't produce seeds
No, pteridophytes do not have seeds. They reproduce via spores, which are released from structures called sporangia on the underside of their leaves. These spores develop into gametophytes that produce eggs and sperm for fertilization.
Gametophytes produce pollen, which is the male gametophyte. Seeds are produced by the fertilization of the female gametophyte by pollen.
in bryophytes the sporophytes is diploid(2n) while the gametophyte in bryophytes is haploid(n).In bryophytes the sporophytes are totally or partially dependent on gametophytes while gametophytes are the dominant generation in bryophytes.Male sporophytes produce male spores and that of female produce megaspores of female spores while male gametophytes produce male gametes while female gametophytes produce female gametes
In gymnosperms, the haploid structures are primarily the gametophytes, which develop from spores. Specifically, the male gametophyte is found within pollen grains, while the female gametophyte is located within the ovule. These gametophytes produce the gametes (sperm and egg cells) necessary for fertilization, completing the life cycle of gymnosperms.
Gametophytes go through mitosis to create gametes (pollen in male gametophyte and egg in female gametophyte)

The gametophytes of gymnosperms are found within the reproductive structures of the plant, such as the male cones for the pollen-producing male gametophytes and the ovules for the egg-producing female gametophytes.
No, pteridophytes do not have seeds. They reproduce via spores, which are released from structures called sporangia on the underside of their leaves. These spores develop into gametophytes that produce eggs and sperm for fertilization.
The gametophytes of gymnosperms live inside reproductive structures called cones. Gametophyte is the immediate result of fertilization in mosses.
Gametophytes produce pollen, which is the male gametophyte. Seeds are produced by the fertilization of the female gametophyte by pollen.

Megasporangia are structures that produce megaspores, which are involved in the formation of female gametophytes in seed-producing plants such as gymnosperms and angiosperms. Megasporangia are typically located within the ovules of the plant's reproductive structures, where they develop into megagametophytes during the process of seed formation.
The spores of gymnosperms are reproductive structures produced in the sporophyte generation. These spores are released from specialized structures called sporangia and develop into male and female gametophytes that produce eggs and sperm for fertilization. Gymnosperms include plants like conifers, cycads, and ginkgoes.
Ferns reproduce through spores produced in structures called sporangia. Sporangia are typically found on the underside of the fronds or in clusters called sori. When the spores are released and germinate, they grow into small heart-shaped structures called gametophytes, which produce eggs and sperm for sexual reproduction.
