Fertilization in humans involves fusion of human egg and sperm in order to form a fertilized egg which is also called as zyroid.
00:18
Now in order to understand what is the correct option, let us see the structures of a human egg and a human sperm.
00:27
So a human egg is basically nothing but an egg which contains a nucleus, inner mass, and zona pellucida.
00:38
Zona pellucida is the outermost lining of the egg cell.
00:46
This is inner mass denoted by im, zona pellucida denoted by zp and this is the nucleus denoted by n.
00:55
On the contrary, the human sperm consists of three parts and a croissant, a collar and a long tail.
01:06
So the acrosome, which is a crosome, which is a also called as head has the nucleus in it.
01:12
This is the collar denoted by a, acrosum denoted by a, collar denoted by c, a corrosome denoted by a and this tail denoted by t.
01:22
Now let's see the functions of the tail first.
01:26
The tail basically helps in motility of the sperm and it drives towards the egg and nothing else.
01:36
So it does not contain any enzymes that could break into the egg cell...
