An archegonium ( pl.: archegonia ), from the Ancient Greek แผฯฯฮฎ ("beginning") and ฮณฯฮฝฮฟฯ ("offspring"), is a multicellular structure or organ of the gametophyte phase of certain plants, producing and containing the ovum or female gamete. The corresponding male organ is called the antheridium. The archegonium has a long neck canal or.

Antheridium. The male sex organ of Vaucheria is the antheridium. Antheridium Structure and Development. The mature antheridium is a cylindrical, tubular, straight, or strongly curved structure opened by a terminal pore. In homothallic species, the antheridium is formed at the end of a short lateral branch along with or before the oogonium.

A= gametophyte, B= archegonium, C = rhizoid, D = antheridium, exposed as small bump if the gametophyte lobe is folded over. As was the case in the mosses, the fern gametophytes produce structures where the egg and the sperm are produced as a result of cells dividing in a particular pattern to produce archegonia (Figure 7-9) and antheridia..

The Gametophyte Generation. Fig.16.3.2.2 Moss life cycle. The leafy shoot of mosses is haploid and thus part of the gametophyte generation. In the common haircap moss, Polytrichum commune (shown here), there are three kinds of shoots: Female, which develop archegonia at their tip.. A single egg forms in each archegonium.; Male, which develop antheridia at their tip.

The oldest fossil evidence of the Peronosporomycetes that has been identified based on oogonium- antheridium complexes is Hassiella monospora from the Lower Devonian Rhynie chert (Taylor et al., 2006).This fossil occurs within degrading plant material and consists of aseptate hyphae 4-6 ฮผm wide (Figure 13.18).Branching is relatively frequent and includes numerous small, sometimes closely.

Other articles where antheridium is discussed: plant reproductive system: The cellular basis:.the male gametangia are called antheridia and the female oogonia or archegonia. A female gametangium with a sterile cellular jacket is called an archegonium, although, like an oogonium, it produces eggs. In most of the plants dealt with in this article, the eggs are produced in archegonia and the.

Fern - Sporangia, Gametophytes, Alternation: The sex organs of ferns are the antheridium and the archegonium. Within the archegonial venter the zygote undergoes cell divisions to form the embryo, which usually has a development distinctive to ferns. Stems are most often in the form of rhizomes, and are usually covered with trichomes.

Antheridium formation was only slightly recovered by transferring to a hormone-free medium, but was significantly rescued by GA medium . However, the recovered antheridium was not formed on cells lined up in series, but on sites where the cells had divided into two or three rows. This finding suggests that such abnormal protonema morphology is.
