What is the difference between syngamy and fertilisation?
Female gametes contain 3 gametes one is egg and two other are antipodal cells. male gametes have two cells . One cell fuse with one egg cell which is called fertilization and other one male cell fuse with other two antipodal cells which is called triple fusion. syngamy is the sum of fertilization and triple fusion
What is . Fusing of a the nucleus of a male sex cell with the nucleus of a female sex cell?
The fusion of the nuclei of the sperm and the egg is called fertilization. This will then form a zygote and, eventually, a new organism with genetic information from both the egg and the sperm.
Why sexual reproduction requires meiosis?
The process of meiosis results in the production of gametes in which the number of chromosomes is reduced by half. During sygamy, two gametes fuse to form a new cell, and the number of chromosomes is restored to the full amount. Therefore, by coupling meiosis and syngamy, the organism ensures that the proper number of chromosomes will be maintained.
The fusion of male and female gamete is called?
The fusion of two haploid gametes to form a new diploid cell is called fertilization. Self-fertilization in plants, the fusion of two gametes from the same individual to form a diploid offspring.
Describe the functions of the gonads?
Gonads are testes and ovaries. Testes produce spermatozoa by spermatogenesis and ovaries produce ova by oogenesis. Spermatozoa are produced via mitosis, producing diploid primary spermatocytes, then meiosis I which produces haploid secondary spermatocytes, which are converted to spermatids by meiosis II. Spermatids become spermatozoa. For the inchoate ovum, a diploid primary oocyte forms, followed meiotically by a haploid secondary oocyte. Ovulation occurs and the secondary oocyte only becomes a true ovum after syngamy. During the process, primary polar bodies become secondary polar bodies and are all rejected.

What are the sites in Reptiles and Amphibians where syngamy occurs?
In amphibians, syngamy occurs in the external medium (water) i.e. outside the body of organism while in reptiles, syngamy occurs inside the body of organism.
Are Syngamy and fertilisation different?
yes
What does Syngamy occur between?
gametes are the correct answer!
What would happen when syngamy not occur?
fertilisation does not take place
What is triple-fertilization?
Double fertilization + syngamy occurring in angiosperms is called triple fusion.
Why fertilisation is also called syngamy?
Syn = together, fusion Gamy = seed. The root word for gametes.
What is the difference between syngamy and fertilisation?
Female gametes contain 3 gametes one is egg and two other are antipodal cells. male gametes have two cells . One cell fuse with one egg cell which is called fertilization and other one male cell fuse with other two antipodal cells which is called triple fusion. syngamy is the sum of fertilization and triple fusion
How do amoebas differ from sporozoan in the way they reproduce?
Amoeba reproduces by binary fission while sporozoans show schizogony , sporogony , gametogony and syngamy .
What is triple fusion.Describe the process of fertilization in an angiosperm plant?
During fertilisation in plants, one male gamete fuses with the egg cell and forms the zygote (this process is called syngamy). The other male gamete fuses with the secondary nucleus (this is called triple fusion). The syngamy and triple fusion together are called double fertilization.
The fusion of male gamete cells with female gamete cells are called what?
The process of gamete fusion is called fertilization. This process forms a diploid cell also known as a zygote.
What is . Fusing of a the nucleus of a male sex cell with the nucleus of a female sex cell?
The fusion of the nuclei of the sperm and the egg is called fertilization. This will then form a zygote and, eventually, a new organism with genetic information from both the egg and the sperm.
What is the definition of fertillzation?
Fertilization (also known as conception, fecundation and syngamy), is the fusion of gametes to produce a new organism. In animals, the process involves a sperm fusing with an ovum, which eventually leads to the development of an embryo. Depending on the animal species, the process can occur within the body of the female in internal fertilisation, or outside in the case of external fertilisation.
