Ova - definition of ova by The Free Dictionar

the female reproductive cell, developed in the ovary; female gamete; egg cell The ovulated oocyte or ovum is surrounded by a zona pellucida cell shell and cumulus cells (Fig. 19.3). The ovulated oocyte is placed in the fimbriae of the fallopian tube and transported through the fallopian tube to the uterus. The mucosa of the fallopian tube provides nourishment to the ovum or zygote (fertilized ovum) Definition All sexually reproducing organisms make sex cells called gametes. The gamete, produced by the female is called the egg or ovum (plural = ova). It joins with the sperm, the male gamete,..

This condition is seen in many common garden plants. A closer analogy to hermaphroditism in botany is the presence of separate male and female flowers on the same individual [citation needed] —such plants are called monoecious Ovum definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation.

It comprised of partial the genetic material necessary to form a complete organism, in other words, it is called Haploid. Gametes are shaped or formed by the process of Meiosis Parasitology is the study of parasites, their hosts, and the relationship between them.As a biological discipline, the scope of parasitology is not determined by the organism or environment in question but by their way of life.This means it forms a synthesis of other disciplines, and draws on techniques from fields such as cell biology, bioinformatics, biochemistry, molecular biology. Schistosoma eggs are eliminated with feces or urine, depending on species .Under appropriate conditions the eggs hatch and release miracidia , which swim and penetrate specific snail intermediate hosts .The stages in the snail include two generations of sporocysts and the production of cercariae .Upon release from the snail, the infective cercariae swim, penetrate the skin of the human host.

The pregnancy rate and the number of ova transferred appear to be directly related. Pope et al. (1972), using noninjected ova, observed that the pregnancy rate at 26-29 days of gestation improved when the number of ova transferred was increased from 12 to 24 (pregnancy rates were 71.4% and 100%, respectively).A similar finding was noted by Brem et al.

Difference Between Ova and Cyst Definition. Ova: Ova refer to the eggs of parasitic worms that are found in the feces as an indicator of parasitic disorders Oogenesis—the differentiation of the ovum—differs from spermatogenesis in several ways. Whereas the gamete formed by spermatogenesis is essentially a motile nucleus, the gamete formed by oogenesis contains all the materials needed to initiate and maintain metabolism and development. Therefore, in addition to forming a haploid nucleus, oogenesis also builds up a store of cytoplasmic enzymes.

Sperms and ova are considered to be the most common examples of gametes. There is a distinct difference in the shape and the size of these 2 reproductive cells or gametes. However, there is one similarity and it is that they are completely haploid in nature Twins account for over 90 per cent of multiple births. There are two types of twins - identical (monozygotic) and fraternal (dizygotic). To form identical twins, one fertilised egg (ovum) splits and develops two babies with exactly the same genetic information. This differs from fraternal twins, where two eggs (ova) are fertilised by two.

One of the paired female reproductive glands containing the ova or germ cells; the ovaries stroma is a vascular connective tissue containing numbers of ovarian follicles enclosing the ova; surrounding this stroma is a more condensed layer of stroma called the tunica albuginea. SYN: ovarium [TA] , female gonad, genital gland (2) . [Mod Gametes are specialized sex cells that contain half the number of chromosomes of the parent. In humans, the female gamete is called an ovum or egg, while the male gamete is called the sperm. Human development begins at fertilization - a process in which a sperm and an egg unite to form a single cell, called the zygote The zygote is a living human child. The anatomy of this uterus is the most usual feature of the ova definition. You will find just six glands, also known as follicles, which secrete. The hatching procedure is additionally crucial. The embryo that's at the uterus during the good right time of hatching have not developed to a whole embryo Once released, egg and sperm alike are destined to die within minutes or hours unless they find each other and fuse in the process of fertilization. Through fertilization, the egg and sperm are saved: the egg is activated to begin its developmental program, and the haploid nuclei of the two gametes come together to form the genome of a new diploid organism

According to the dictionary definition, binary means consisting of, indicating, or involving two. As a biologist, I can confidently say this definition accurately describes biological sex. That is because the sex of an individual refers to one of two—and only two—functional roles that an individual may play in sexual reproduction However, the ova has to be rich in cytoplasmic contents in order to compensate for the lesser amount of cytoplasm in the sperm, so that the zygote has enough of cytoplasm. Therefore, there is an unequal division of the oogonium, so that the ovum is larger ovum: Plant Ova. In plants that reproduce sexually the pattern is similar to that of animals. In the mosses and ferns, however, the egg cells are formed in special organs called archegonia and are fertilized by sperm that are commonly flagellated and motile like those of animals. In flowering plants the ovary is situated in the base of the. Fertilization. Fertilization is the process in which gametes (an egg and sperm) fuse to form a zygote. The egg and sperm are haploid, which means they each contain one set of chromosomes; upon fertilization, they will combine their genetic material to form a zygote that is diploid, having two sets of chromosomes Mice (4 mice/group/experiment) receiving the following treatments were studied: (1) nonsensitized and nonchallenged mice, and (2) OVA-sensitized and OVA airway-challenged mice (OVA/OVA).Mice were immunized by intraperitoneal injection of 20 μg OVA (Grade V; Sigma, St. Louis, MO) emulsified in 2.25 mg alum (AlumImuject; Pierce, Rockford, IL) in a total volume of 100 μl on Days 0 and 14 oviduct tube to carry eggs from the ovary Source: Noland, George B. 1983.
