Image Gray8.png thumb 400px The process of fertilization in the ovum of a mouse. A pronucleus plural pronuclei is the nucleus of a sperm or an egg cell during the process of fertilization , after the sperm enters the ovum, but before they fuse. Sperm and egg cells are Ploidy haploid , meaning they carry half the number of chromosome s. When the pronucleus of a sperm fuses with the pronucleus of an egg, their chromosomes combine and become part of a single diploid nucleus in the resulting embryo , containing a full set of chromosomes. The appearance of two pronuclei is the first sign of successful fertilization as observed during in vitro fertilisation , and is usually observed 18 hours after insemination or ICSI. The zygote is then termed a two pronuclear zygote 2PN . Two pronuclear zygotes transitioning through 1PN or 3PN states tend to develop into poorer quality embryos than ones who remain 2PN throughout development, ref cite journal author Reichman DE, Jackson KV, Racowsky C title Incidence and development of zygotes exhibiting abnormal pronuclear disposition after identification of two pronuclei at the fertilization check journal Fertil.

According to the principle of nuclear equivalence , the nuclei of essentially all differentiated adult cells of an individual are genetically though not necessarily metabolically identical to one another and to the nucleus of the zygote from which they descended. This means that virtually all somatic cells in an adult have the same genes. However, different cells express different subsets of these genes. The evidence for nuclear equivalence comes from cases in which differentiated cells or their nuclei have been found to retain the potential of directing the development of the entire organism. Such cells or nuclei are said to exhibit totipotency . ref cite book last Solomon, Berg, Martin first Eldra, Linda, Diana W. title BIOLOGY, 9th edition year 2011 publisher Brooks Cole isbn 978 1 111 77437 0 pages 370 ref References reflist Uncategorized date April 2012 ... more details

Filamentous means the colony is one cell thick. Reproduces in two ways sexually and asexually. Reproduces sexually through syngamy . The anthridia which produces sperm and the oogonium which produces the egg, release the sperm and egg. The egg and sperm then fuse and form a zygote 2n . The zygote then produces the filamentous green algae which is haploid 1n . The oedogonium can also produce asexually through zoospores. These separate from the parent plant through the zoosporangium and continue to divide producing the filamentous green algae. Oedogium is usually freefloating when mature though it can be attached to plants. Lives in quiet, fresh water. It has a spirally shape with a greenish tinge to it DISTRIBUTION OF SEX ORGAN species of oedogonium are divided into the following two groups on the basis of distribution of sex organ A MACRANDOUS SPECIES In these species antheridia are borne on the filament of normal size. where antheridia and oogonia are found on the same filament, are called MACRANDOUS MONOECIOUS. and where anthredia and oogonia are borne on the different filament, are known as MACRANDOUS DIOECIOUS. Although filament bearing anthredia and oogonia are morphologically similar, they differ physiologically. B NANNANDROUS SPECIES In nannandrous species filament bearing anthredia and oogonia show morphilogical distinction. the male filament, which are much smaller than the female filament, are called dwarf male or nannandrium. nannandrous species are always dioecious, i.e., anthridia and oogonia are borne on different filaments.

Micrasterias, commonly known as green alga, is a Eukaryotic, unicellular, and 0.35mm in size. Micrasterias displays a bilateral symmetry, with two mirror image semi cells joined by a narrow isthmus containing the nucleus of the organism. This dual semi cell structure is unique to the group of green algae to which Micrasterias belongs. Each semi cell contains a single large chloroplast, the site of photosynthesis for the Micrsterias. Chloroplasts within Micrasterias contain chlorophylls A and B and the enzymes required for photosynthesis. The sugar created is used to provide energy for the organism or, if not used, taken up by many small round pyrenoids which are embedded in the chloroplast. They convert the sugar to a starch for storage. Micrasterias can produce both asexually and sexually. Asexual reproduction occurs via mitosis. When this occurs the genetic material of Micrasterias is duplicated and two small semi cells grow between the original semi cells, gradually increasing in size. Sexual reproduction occurs through a process called conjugation whereby two organisms come together and fuse their haploid cells to form a diploid zygote. This zygote typically forms a thick protective wall which can allow the organism to remain dormant for many months to survive cold winters and long droughts. When good conditions resume, the zygospore will germinate, undergo meiosis, and produce new haploid algal cells. External links http protist.i.hosei.ac.jp PDB Images Chlorophyta M ... more details
Refimprove date December 2009 Image Sperm egg.jpg thumb Oogamy in animals small, motile sperm on the surface of large egg cell Oogamy is the familiar form of sexual reproduction . It is a form of anisogamy heterogamy in which the female gamete e.g. Ovum egg cell is significantly larger than the male gamete and is non motile. The male gametes are typically highly motile spermatozoon spermatozoa competing for the fertilization of the immotile egg. By contrast to isogamy , the gametes are specialized. The ovum contains nearly all of the materials that will be needed by the zygote after fertilization, but it typically cannot move. The sperm contains almost nothing but the male genetic contribution to the zygote, but it is usually tasked with all of the travel necessary to bring the respective gametes together. The prevalence of oogamy in higher animals leads to the conclusion that this specialization of the gametes results in their performing their respective tasks better and more efficiently than those tasks could be performed by generalist isogametes, particularly the ability to concentrate high energy substances in a smaller number of ova. Oogamy predominantly occurs in animal s, but can also be found in many protist s, certain orders of algae Ochrophyte s, Charophyta Charophyceans , and some plants such as bryophyte s, fern s, and some gymnosperm s like cycad s and ginkgo . In some algae, most gymnosperms and all angiosperm s, a variation of oogamy occurs where the sperm cells are non motile as well. It appears that isogamy was the first stage of sexual reproduction . In several lineages, this form of reproduction independently evolved to anisogamy with gamete s of male and female types to oogamy. There is a good argument that this pattern was driven by the physical constraints on the mechanisms by which two gametes get together as required for sexual reproduction . ref Dusenbery, David B. 2009 .

It was observed for the first time by Antoni van Leeuwenhoek in 1674. Life cycle The rabbits ingest sporulated oocysts . Sporulated oocysts contain four sporozoites that hatch and travel via the hepatic portal vein to the liver, and eventually penetrate the bile duct epithelium , where they undergo asexual reproduction known schizogony . Rupture of the schizont consequently causes epithelial cell rupture and death. Merozoites will penetrate other cells and create more merozoites for one to several rounds. Eventually, a merozoite becomes a male microgamecyte and asexually reproduces in epithelial cells. A ruptured microgamecyte infects a cell with the female macrogamecyte and through sexual reproduction create a zygote . The zygote develops a protective shell before expulsion in the bile excreation and then the feces as an oocyst. Pathogenesis and Pathology The schizonts in the bile duct cause bile duct hyperplasia , and blockage of bile ducts leading to hepatomegaly and hence icterus . Due to liver failure, the abdomen will be distended with fluid. Diagnosis The presence of oocysts on fecal flotation or impression smear of the liver are diagnostic for coccidiosis .

For human prenatal development prenatal development unreferenced date January 2009 Prenatal development is the process in which an immature individual develops before birth . For instance, mammalian prenatal development is the process where an embryo or fetus or foetus gestation gestates during pregnancy , from fertilization until birth . Prenatal development starts with fertilization, which marks the beginning of embryogenesis. Embryogenesis, in turn, continues in fetal development, which lasts until birth. Fertilization Main Fertilisation Fertilisation or fertilization also known as conception, fecundation and syngamy , is fusion of gametes to form a new organism of the same species. In animals, the process involves a sperm fusing with an ovum, which eventually leads to the development of an embryo. Depending on the animal species, the process can occur within the body of the female in internal fertilization, or outside in the case of external fertilization. Embryogenesis Main Embryogenesis Embryogenesis is the process by which the embryo is formed and develops. It starts with the fertilization of the ovum or oocyte also known as the egg , which, after fertilization, is then called a zygote. The zygote undergoes rapid mitotic divisions, the formation of two exact genetic replicates of the original cell, with no significant growth a process known as cleavage and cellular differentiation, leading to development of an embryo. It occurs in both animal and plant development. Fetal development Main Fetus biology In viviparous organisms, the embryonic stage is succeeded by the fetal stage. Often, however, the term fetal development is used in a similar sense to prenatal development . References reflist colwidth 30em 1. The bioloy of prenatal development. n.d. .

Isolecithal Greek iso equal, lekithos yolk refers to the even distribution of yolk in the cytoplasm of ovum s of mammal s and other vertebrates , notably fishes of the families Petromyzontidae , Amiidae , and Lepisosteidae . Isolecithal cells have two equal hemispheres of yolk. However during cellular development, normally under the influence of gravity, some of the yolk settles to the bottom of the egg, producing an uneven distribution of yolky hemispheres. Such uneven cells are known as telolecithal and are common where there is sufficient yolk mass. In the absence of a large concentration of yolk, four major cleavage types can be observed in isolecithal cells radial holoblastic , spiral holoblastic, bilateral holoblastic, and rotational holoblastic cleavage. These holoblastic cleavage planes pass all the way through isolecithal zygote s during the process of cytokinesis . Coeloblastula is the next stage of development for eggs that undergo this radial cleavaging. In mammals, because the isolecithal cells have only a small amount of yolk, they require immediate implantation onto the uterine wall to receive nutrients.
