Who discovered triple fertilization?
- Now, the double fertilization and the triple fusion is first discovered by Nawaschin and Guignard.
Who discovered double and triple fertilization?
The explanation for Correct Answer: Double fertilization was discovered by Nawaschin and Guignard. Syngamy and triple fusion occur during double fertilization, resulting in the production of a zygote and a primary endosperm nucleus, respectively.
Who first suggested that double fertilization?

What is double fertilization 1st?
Double fertilization is a complex process where out of two sperm cells, one fuses with the egg cell and the other fuses with two polar nuclei which result in a diploid (2n) zygote and a triploid (3n) primary endosperm nucleus (PEN) respectively.
Who discovered fertilization in plants first?
The process of fertilization in plants was first discovered by Strasburger (1884).
Who first discovered fertilization?
The history of the discovery by O. Hertwig (1875-1878) of the very nature of fertilization--the fusion of the egg's and spermatozoon's nuclei--is presented. In result, the principle of continuity of the nuclear structures in embryonic development was proclaimed.
When did scientists discover fertilization?
The scientific identification of the key components of sexual reproduction - eggs and sperm - took place during an amazing decade of discovery in the 1660s and 1670s.

The first undisputed observation of the human ovum was made by Karl Ernst von Baer (1792-1876), and reported in a letter in 1827.
Who discovered reproduction?
The particular cellular characteristics of sea urchins allowed Oscar Hertwig to observe the process clearly under the microscope and achieve his greatest success, which he published in 1876: fertilisation occurs when the sperm enters the egg and its nuclei fuse, between 5 and 10 minutes later.Apr 17, 2019
