FAQs on Process of Fertilization Video Lecture - Class 8

1. What is fertilization?
Ans. Fertilization is the process by which a male gamete (sperm) fuses with a female gamete (egg) to form a zygote, which eventually develops into a new individual.
2. How does fertilization occur in humans?
Ans. In humans, fertilization occurs when a sperm cell from the male fuses with an egg cell from the female in the fallopian tube. This usually happens during sexual intercourse.
3. What is the role of sperm in fertilization?
Ans. The sperm carries the male genetic material and is responsible for fertilizing the egg. It has a long tail that helps it swim towards the egg and a head that contains enzymes to break down the protective layers of the egg.
4. What happens after fertilization?
Ans. After fertilization, the zygote undergoes a series of cell divisions called cleavage. It then travels down the fallopian tube and implants itself into the lining of the uterus. From there, it develops into an embryo and eventually a fetus.
5. Can fertilization occur outside the body?
Ans. Yes, fertilization can occur outside the body through a process called in vitro fertilization (IVF). In IVF, the egg and sperm are combined in a laboratory dish, and once fertilization occurs, the resulting embryo is transferred to the woman's uterus for implantation.
