Gamete vs. Gonad - What's the difference?

Main Difference

The main difference between Gamete and Gonad is that the Gamete is a haploid cell that fuses with another haploid cell during fertilization (conception) in organisms that sexually reproduce and Gonad is a endocrine gland that produces the gametes of an organism.

  • Gamete

    A gamete (; from Ancient Greek γαμετή gamete from gamein "to marry") is a haploid cell that fuses with another haploid cell during fertilization in organisms that sexually reproduce. In species that produce two morphologically distinct types of gametes, and in which each individual produces only one type, a female is any individual that produces the larger type of gamete—called an ovum— and a male produces the smaller tadpole-like type—called a sperm. In short a gamete is an egg cell (female gamete) or a sperm (male gamete). This is an example of anisogamy or heterogamy, the condition in which females and males produce gametes of different sizes (this is the case in humans; the human ovum has approximately 100,000 times the volume of a single human sperm cell). In contrast, isogamy is the state of gametes from both sexes being the same size and shape, and given arbitrary designators for mating type. The name gamete was introduced by the Austrian biologist Gregor Mendel. Gametes carry half the genetic information of an individual, one ploidy of each type, and are created through meiosis. Oogenesis is the process of female gamete formation in animals. This process involves meiosis (including meiotic recombination) occurring in the diploid primary oocyte to produce the haploid ovum. Spermatogenesis is the process of male gamete formation in animals. This process also involves meiosis occurring in the diploid primary spermatocyte to produce the haploid spermatozoon.

  • Gonad

    A gonad, sex gland, or reproductive gland is a mixed gland that produces the gametes (sex cells) and sex hormones of an organism. In the female of the species the reproductive cells are the egg cells, and in the male the reproductive cells are the sperm. The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells. Both of these gametes are haploid cells.

Wiktionary

  • Gamete (noun)

    A reproductive cell (sperm in males or eggs in females), having only half of a complete set of chromosomes.

  • Gonad (noun)

    A sex organ that produces gametes; specifically, a testicle or ovary.

  • Gonad (noun)

    The testicles.

Oxford Dictionary

  • Gamete (noun)

    a mature haploid male or female germ cell which is able to unite with another of the opposite sex in sexual reproduction to form a zygote.

  • Gonad (noun)

    an organ that produces gametes; a testis or ovary.

  • Gonad (noun)

    a man's testicles or genitals.

Webster Dictionary

  • Gamete (noun)

    A sexual cell or germ cell having a single set of unpaired chromosomes; a conjugating cell which unites with another of like or unlike character to form a new individual. In Bot., gamete designates esp. the similar sex cells of the lower thallophytes which unite by conjugation, forming a zygospore. The gametes of higher plants are of two sorts, sperm (male) and egg (female); their union is called fertilization, and the resulting zygote an oöspore. In Zool., gamete is most commonly used of the sexual cells of certain Protozoa, though also extended to the germ cells of higher forms.

  • Gonad (noun)

    One of the masses of generative tissue primitively alike in both sexes, but giving rise to either an ovary or a testis; a generative gland; a germ gland.

Princeton's WordNet

  • Gamete (noun)

    a mature sexual reproductive cell having a single set of unpaired chromosomes

  • Gonad (noun)

    a gland in which gametes (sex cells) are produced
