gamete

 [gam´ēt]
1. one of two haploid reproductive cells, male (spermatozoon) and female (oocyte), whose union is necessary in sexual reproduction to initiate the development of a new individual.
2. the malarial parasite in its sexual form in a mosquito's stomach, either male (microgamete) or female (macrogamete); the latter is fertilized by the former to develop into an ookinete. adj., adj gamet´ic.

gam·ete

(gam'ēt),
1. One of two haploid cells that can undergo karyogamy.
2. Any germ cell, whether oocyte or sperm.

gamete

(găm′ēt′, gə-mēt′)
n.
A reproductive cell having the haploid number of chromosomes, especially a mature sperm or egg capable of fusing with a gamete of the opposite sex to produce a zygote.

gamete

[gam′ēt]
Etymology: Gk, marriage partner
1 a mature male or female germ cell that is capable of functioning in fertilization or conjugation and contains the haploid number of chromosomes of the organism.
2 an ovum or a spermatozoon. See also meiosis. gametic, adj.

gamete

Genetics A mature ♀ or ♂ reproductive cell–sperm or ovum/egg with a haploid set of chromosomes–23 for humans. See Chromosome, Haploid, Macrogamete, Microgamete, Nullisomic gamete.

gamete

A cell, such as a sperm or ovum, possessing half the normal number of chromosomes (haploid) and capable of fusing with another gamete in the process of fertilization, so that the full (diploid) number of chromosomes is made up. From the Greek gamos , marriage.

gamete

or

germ cell

a specialized HAPLOID cell that fuses with a gamete from the opposite sex (or mating type) to form a diploid ZYGOTE. In simple organisms, the process is called isogamy (see ISOGAMETE), and OOGAMY in more complex organisms. In animals where oogamy occurs male gametes are called sperm, the female gametes eggs. The situation in higher plants is more complicated, but essentially the male gamete is the generative nucleus found in the POLLEN GRAIN while the female gamete is the egg cell found within the EMBRYO SAC.

Gamete

An egg (ovum) from the female or a mature sperm from the male.

gamete

The major presence of mannose ([alpha] 1-3) mannose, detected by GNL lectin, and N-acetyl-glucosamine on the envelopes of different maturation stage oocytes of R, typus might be attributable to the eventual participation of these sugars in the primary or secondary gamete interaction as demonstrated in Phallusia mammillata, where N-acetyl-glucosamine as well as N-acetyl-galactosamine are implicated in the primary gamete interaction (Honegger, 1982; Litscher & Honegger, 1991) and they are the highest quantity on those oocyte envelopes (Litscher & Honegger, 1991).

The reproductive system is composed of a) a single gonad, b) a renopericardial duct that transport the gametes to the distal portion of the right kidney, it has a gland attached to its inner wall and is connected by the nefrostome to the pericardium; and c) the distal portion of the right kidney which receives the gametes from the duct.
