Difference Between Male and Female Gametes

关键区别 - 男性与女配子

有性繁殖是一种复制形式，形成了两种类型的联合的新个体配子。配子是一个成熟的单倍体male or femalegerm cellwhich is capable of fusing with another germ cell of the opposite sex to form azygote。Gametes vary in structure (anisogamete) and motility and are produced by different parents. Some female and male gametes are similar in some characteristics such as size, and shape. In some species offungi and algae，两种配子类型几乎相同。在较高的动植物中，雄性配子又小又流动，而女配子却大且非活力。当男配子互相融合时（fertilization), the resulting cell, i.e., diploid zygote, contains two sets of染色体。男配子被称为spermsand they are produced by the male organism or male reproductive organ. Female gametes are known asegg cellsand they are produced by the female organism or female reproductive organ。This is the key difference between male and female gametes.

什么是男配子？

Male haploid sex cells are known as male gametes. Male gametes are different in structure and motility among organisms. In higher plants, male gametes are known as花粉grains. They are produced inside the pollen sacs. Pollen sacs reside in the anthers of the male reproductive structures of flowers. Once the pollen grains are formed, they are released to the environment using several mechanisms. These pollen grains are deposited on the stigma of the female reproductive part (皮卡) and male nuclei reach theovaryof the flower to fuse with the egg cell.

In humans, male gametes are known assperms。精子develop in the testes of males. A sperm cell is a small and motile cell. It contains aflagellum，这有助于精子细胞推动并朝着女性细胞移动。精子细胞的头部区域具有类似帽的覆盖物，称为Acrosom，其中含有有助于穿透卵细胞外覆盖的酶。精子细胞到达卵细胞核后，它将融合并产生二倍体细胞。

精子are produced and released in large numbers at a time. They are able to travel through the female reproductive tract and fertilize the female gamete. In non-flowering plants, especially in裸子植物, male gametes are produced in pollen cones.

什么是女配子?

女配子是由女性生物体产生的性细胞，用于有性繁殖。它们被称为卵细胞。卵细胞是含有一组染色体（N细胞）的成熟单倍体细胞。通常，女配子比男配子大。与精子不同，它们也是非运动的。在开花植物中，卵细胞在卵巢中产生。每个地球都有一个卵巢胚珠。每个胚珠都包含一个雌性配子的鸡蛋细胞。

女性产生的配子减数分裂和fertilized with the sperm within the female body of mammals.

男女配子之间有什么相似之处？

• Male and female gametes contain one set of chromosomes.
• 两个配子都参与性繁殖，它们是性细胞。
• 两个配子都是由meiosis。
• 两个配子都参与了合子的形成。

What is the Difference Between Male and Female Gametes?

男性与女配子
雄配子是由雄性生物或雄性生殖器官产生的成熟单倍体细胞。	女配子是由女性生物或女性生殖器官产生的成熟单倍体细胞。
Size
Male gametes are generally smaller than female gametes.	Female gametes are larger than male gametes.
植物生产
In higher plants, male gametes are produced inside pollen sacs of the anthers.	In higher plants, female gametes are produced inside the ovary.
产生的配子数量
Male gametes are produced in large numbers compared to female gametes.	Female gametes are produced in small numbers.
Reaching Opposite Sex Cell
In higher plants, male gametes (pollen grains) are transferred to the stigma of another flower by external agents such as insects or the wind.	In higher plants, female gametes remain immobile inside the ovary of the flower.

摘要 - 男性与女配子

Gametes are haploid sex cells produced for sexual reproduction. Male gametes are male sex cells and female gametes are female sex cells. Gametes are produced by meiosis. They contain only one set of chromosomes. Two opposite sex gametes fuse with each other and produce a diploid zygote which develops into a new organism. In different organisms, gametes vary in size, shape, motility, etc. Generally, male gametes are smaller than female gametes and motile. However, in certain species of fungi and algae, identical male and female gametes can be seen. In higher organisms, male and female gametes can be clearly distinguished. Male gametes are known as sperms while female gametes are known as egg cells. This is the difference between male and female gametes.
