What is the function of archegonia and antheridia?

What is the function of archegonia and antheridia?

Therefore, both antheridium and archegonium are haploid. Their main function is to produce gametes. Ultimately, the fertilization of haploid gametes gives rise to the diploid zygote, which in turn develops into the sporophyte.

What do archegonia and antheridia have in common?

They are also monoecious – both the archegonia and antheridia (male and female reproductive structures) are borne on the same plant. Contrast these primitive vascular plants with the more advanced seed plants, the gymnosperms and angiosperms, which germinate from seeds rather than from spores.

What is the function of antheridia?

Antheridia is the male sex organ and its function is to produce gametes called antherozoids. The female equivalent organ is the archegonia, which produces the egg cells.

What are antheridia plants?

The male sex organ, the antheridium, is a saclike structure made up of a jacket of sterile cells one cell thick; it encloses many cells, each of which, when mature, produces one sperm. The antheridium is usually attached to the gametophyte by a slender stalk.

Where is the antheridia located?

Male sex organs known as antheridia and female sex organs, which are referred to as archegonia, are typically located at the tips of the main shoots of gametophyte mosses.

What process occurs inside antheridia and archegonia?

In the antheridia of the plant, the sperm cells are formed, whereas inside of the archegonia, the egg cells are formed. Once the haploid egg and the haploid sperm meet, they fuse, creating a diploid organism.

What is the difference between the antheridia and the archegonia?

Hint: Antheridia is the male sex organ, and is a haploid structure whose function is to produce male gametes called antherozoids or sperms. Archegonia is the female sex organ, which produces female gametes mainly in cryptogams. It is responsible for the production of female gametes that are egg cells or ova.

What is the function of archegonium?

The archegonium also serves as the site of fertilization. After the egg is fertilized, the egg will remain in the archegonium until it develops into a sporophyte. A sporophyte is the spore-producing form of the plant. The archegonium releases the sporophyte once it has fully developed.
