Example: egg cells or ova. This condition is named oogamy, wherein a large non-motile egg is fertilized or will fuse with a small and motile sperm to form the zygote. It is named male gamete or sperm cell. In animals, these reproductive cells are produced in respective male and feminine gonads or reproductive organs. In animals, anisogamy is seen, wherein the construction of the male gamete is totally different from the feminine gamete. They could also be summary ideas embodied in tangible shape, such as the horrible creature, the kind of some divine high quality, that stands calm, immovable, and imperishable within the walls of our National Museum; such varieties as the dragon, of the purely imaginative class, and those creatures compounded of elements of different real animals, yet unlike any certainly one of them, each possessing particular symbolic attributes, according to the standard ideas held regarding them. Oogamy: in humans and mammals, one of many gametes, male gamete or sperm, is motile and the opposite gamete, egg, or feminine gamete is non-motile. In the terminology used to explain the sex and age of cattle, the male is first a bull calf and if left intact becomes a bull; if castrated he becomes a steer and about two or three years grows to an ox.

In seed-bearing plants, the male gametes are the pollen while the female gametes are enclosed within the ovules of the plant.
What are the various kinds of gametes? All these gametes are categorized as ‘female’ and ‘male’. These kinds of gametes are usually not categorized as ‘male’ or ‘female’. Both males and feminine gametes are formed by a process known as “gametogenesis” of their respective reproductive organs. Males retained for beef manufacturing are normally castrated to make them extra docile on the range or in feedlots. Most steers are raised for beef manufacturing.

The gametogenesis that results in the formation of sperm is known as “spermatogenesis” whereas the means of formation of egg or ova is known as “oogenesis”.
This is also the longest part of the sperm cell. During the technique of gametogenesis, a diploid (2n) cell undergoes meiosis to provide four haploid (n) cells. A gamete is the mature reproductive or intercourse cell that contains a haploid variety of chromosomes (i.e., 50% of the genetic materials or only one set of dissimilar chromosomes) and is able to fusing with another haploid reproductive cell to kind a diploid zygote. Isogamy: gametes with related morphology i.e., size and form. Microgametes: gametes which can be smaller in measurement. The gamete with a smaller size is known as sperm or male gamete whereas the gamete with a bigger dimension is known as ova or egg or female gamete. The motile organ of the sperm is understood because the flagellum. Non-motile male gamete or sperm is known as spermatia. The non-motile male gamete in plants is named pollen. This can be seen in certain flowering plants whereby both the gametes are non-motile and are current within the gametophyte. Anisogamy: gametes with dissimilar morphology i.e. dimension and shape. Another approach of classification of the gametes relies on their size. Macrogametes: gametes which are larger or bigger in dimension.
