Hermaphrodite. v. t. e. A gamete(/ˈɡæmiːt/; from Ancient Greek γαμετή(gametḗ) 'wife', ultimately from Ancient Greek γάμος(gámos) 'marriage') is a haploid cellthat fuses with another haploid cell during fertilizationin organismsthat reproduce sexually.[1] Gametes are an organism's reproductive cells, also referred to as sex ...
Gonochorism. Hermaphrodite. v. t. e. Gametogenesis is a biological process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid gametes. Depending on the biological life cycle of the organism, gametogenesis occurs by meiotic division of diploid gametocytes into various gametes, or by mitosis.
A gametid is a complementary gamete to the gamete that gives rise to a zygote after conception. During meiosis, four gametes, or haploid cells, are the products of diploid cell division. Two gametes, one egg and one sperm, unite during conception, yielding a zygote. For each gamete that makes a zygote, there is a complementary gamete, or ...
Gametocyte. Scheme showing analogies in the process of maturation of the ovum and the development of the spermatids. A gametocyte is a eukaryotic germ cell that divides by mitosis into other gametocytes or by meiosis into gametids during gametogenesis. Male gametocytes are called spermatocytes, and female gametocytes are called oocytes.
Gametophyte. A gametophyte (/ ɡəˈmiːtəfaɪt /) is one of the two alternating multicellular phases in the life cycles of plants and algae. It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes. The gametophyte is the sexual phase in the life cycle of plants and algae.
A gonad, sex gland, or reproductive gland[ 1 ] is a mixed gland and sex organ that produces the gametes and sex hormones of an organism. Female reproductive cells are egg cells, and male reproductive cells are sperm. [ 2 ] The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells.
Megagametogenesis is the process of maturation of the female gametophyte, or megagametophyte, in plants. [ 1 ] During the process of megagametogenesis, the megaspore, which arises from megasporogenesis, develops into the embryonic sac, in which the female gamete is housed. [ 2 ] These megaspores then develop into the haploid female gametophytes ...
Isogamy ( Ancient Greek ισο - iso = "equal + γάμος gámos = "marriage") – in cell biology – is a type of sexual reproduction that includes gametes of similar morphological similar shape and size, with difference in general only in genome content and gene expression in one or more mating-type regions. Both gametes look alike, and ...
