Published by

In a flower the stamens (Anthers)produce pollen grain by meiosis so the pollen grains are the gametophytes (They are haploid and produce male … In contrast to bryophytes, in which the sporophyte is nutritionally dependent on the gametophyte during its entire existence, the fern sporophyte is dependent on the gametophyte for nutrition only during the early phase of its development; thereafter, the fern sporophyte is free-living. There is an evolutionary trend from sporophytes that are nutritionally dependent on autotrophic (self-feeding) gametophytes to the opposite‐gametophytes that are dependent on autotrophic sporophytes.

Bryophytes ( mosses, liverworts and hornworts) have a dominant gametophyte phase on which the adult sporophyte is dependent for nutrition.

C.gametophyte cells come about by mitosis; sporophyte cells come about by meiosis.

In some ferns the sexes are separate, meaning a gametophyte will bear only male or female sex organs. In this group of organisms gametophyte is dominant while the sporophyte is restricted to the zygote (2).

The embryo sporophyte develops by cell division of the zygote within the female sex organ or archegonium, and in its early development is therefore nurtured by the gametophyte.


The In  In the seed plants, the gametophyte develops partly or entirely while attached to and nutritionally dependent on the sporophyte. The heart-shaped prothallia produce gametes that unite to form a zygote, which develops into a new sporophyte plant.This colored scanning electron micrograph (SEM) shows pollen tubes (orange) on the pistil of a prairie gentian flower (Gentiana sp.).

The bryophyte gametophyte is longer lived, nutritionally independent, and the sporophytes are typically attached to the gametophytes and dependent on them.
