Question

A fertilization membrane is formed to_______.

Answer 1

Fertilization:

1. The fusion of male and female gametes to form a zygote is known as fertilization.
2. During copulation, sperm is released from the penis, a male reproductive organ, into the vagina, a female reproductive organ.
3. These movable sperms entered the uterus and eventually made their way to the fallopian tubes. When the ovum and sperm fuse in the fallopian tubes, fertilization occurs.
4. Fertilization occurs in the fallopian tubes, which connect the ovaries to the uterus.
5. When sperm and ovum come into contact, the ovum's membrane (zona pellucida) changes, preventing other sperms from entering. It is critical that only one sperm fuse with the ovum.
6. Acrosomal secretions play an important role in sperm entry. This aids in the completion of the secondary oocyte's meiotic division.
7. The formation of a second polar body and haploid ovum is aided by this secondary meiotic division.
8. After fertilization, a newly fertilized egg known as a zygote (diploid) is formed.

Final answer: A fertilization membrane is formed to prevent multiple fertilization.
