ANTHERIDIUM : - An antheridium is a haploid structure or organ producing and containing male gametes(called antherozoids or sperm). The plural form is antheridia, and a structure containing one or more antheridia is called an androecium."Androecium" is also used as the collective term for the stamens of flowering plants.
Antheridia are present in the gametophytephase of cryptogams like bryophytes and ferns. Many algae and some fungi, for example ascomycetes and water moulds, also have antheridia during their reproductivestages. In gymnosperms and angiosperms, the male gametophytes have been reduced to pollen grains and in most of these the antheridia have been reduced to a single generative cell within the pollen grain. During pollination, this generative cell divides and gives rise to sperm cells.
