The explanation of the answer is that in the process of fertilization, the sperm cell binds to be receptor, present on the outer surface of the egg.
00:11
This triggers certain chemical reaction and eventually leads to the entry of the sperm cell into the egg.
00:26
The sperm cell fertilizes the mature egg.
00:30
This fertilized mature egg is called the zygote.
00:36
Therefore, there is no change in the size or volume as the mature egg represents the zygote on fertilization.
00:46
Hence, we can conclude that there is no difference in size between the zygote and the mature eggs.
00:56
Therefore, the option b is incorrect.
01:00
For the next, the fusion of an egg with the spum cell gives rise to a zygote.
01:09
The zygote is eventually single, called and diploid in nature.
01:16
It contains two sets of chromosomes...
