关键区别 - 血浆果与核果
受精是一个主要阶段sexual reproductive真核生物的循环。期间fertilization, twogametes彼此融合以产生diploidzygote后来成为新个人。受精过程中两个配子的融合称为合成。合伙可以分为两个阶段,名为浆果瘤和核果。血浆首先发生,其次是核果。在某些生物体中,这两种同时发生,而在某些物种中,核对体延迟了相当长的持续时间。血浆果和核对体之间的关键区别在于plasmogamy is the fusion of细胞膜和细胞质of two cells without the nuclei fusionwhilekaryogamy refers to the fusion of two haploid nuclei to produce adiploidcell.

What is Plasmogamy?
The fusion of male and female gametes occurs in sexual reproduction in order to produce a diploid zygote. This is known as fertilization or syngamy. Prior to haploid nuclei fusion, cell membranes of the two gametes fuse and the two cytoplasm fuse with each other. The nuclei fusion delays for a certain time period. This process is known as plasmogamy. Plasmogamy is feasible among two gametes or between two vegetative cells of fungi which play the role of gametes. Plasmogamy is one stage of sexual reproduction infungi它使两个核彼此接近以进行融合。浆果产生了一个与正常单倍体或二倍体细胞不同的新细胞阶段,因为它包含在同一细胞质中共存的雄性和雌性核,而不像N+N状态合并。在此阶段,所得的单元被称为双核体或者dikaryotic cell。硅藻细胞包含两种交配类型的几个核。
什么是核配?
Karyogamy is the step which makes the diploid zygote. Two haploid nuclei fuse with each other to produce diploid zygote. Karyogamy occurs after the fusion of the two cytoplasms. This fusion of two nuclei produces a diploid cell, which has a mixture of two types of genetic materials.
Plasmogamy and karyogamy are clearly visible stages in fungal sexual reproduction. Fungi reproduce through plasmogamy, karyogamy, and减数分裂。这些是真菌性繁殖的主要阶段。这个二口气阶段在大多数真菌中都是突出的,在某些真菌中,它的存在多达几代。然而,在较低的真菌中,核糖膜立即发生在血浆凝胶之后。
ASCOMYCOTA是一组大芬基,在有性繁殖过程中显示出不同的浆果,核和减数分裂的不同阶段。两种类型的菌丝的交配由于浆细菌而产生二克罗尼(N+N)相。之后,核对体发生并产生二倍体合子。然后,二倍体合子通过两个减数分裂师分为八个子肠孢子。

概括– Plasmogamy vs Karyogamy
The fusion of two gametes during sexual reproduction is known as syngamy. Syngamy occurs via two stages named plasmogamy and karyogamy. Plasmogamy is the first stage of syngamy. It is the fusion of the cytoplasm of two gametes or two mating cells without the fusion of their nuclei. Plasmogamy brings the male and female nuclei together. When plasmogamy occurs, it produces a cell which contains two nuclei inherited from each parent and the cell is known as a dikaryotic cell. After the fusion of cytoplasm, two nuclei come closer and fuse with each other. This stage is known as karyogamy. This is the difference between plasmogamy and karyogamy. Once karyogamy occurs, it yields a diploid cell called zygote. The zygote can divide by meiosis to produce spores or it can divide by mitosis to produce a new individual. In some organisms, karyogamy occurs immediately after the plasmogamy as in lower fungi. In some species, dikaryon phase exists for several generations.
