Explanation
Fertilization is the process of sexual reproduction where a sperm cell penetrates and fuses with an egg cell. This occurs in animals including humans and in flowering plants where pollen fuses with the ovule. In humans, fertilization typically occurs in the fallopian tube after intercourse. The resulting zygote contains genetic material from both parents, ensuring genetic variation. This is fundamental to the continuity of species.
Example
In humans, when a sperm cell meets an ovum in the fallopian tube after intercourse, fertilization occurs and the zygote begins cell division to form an embryo.
Frequently Asked Questions
Where does fertilization occur in humans?
Fertilization typically occurs in the fallopian tube (oviduct) after sperm enters the female reproductive tract.
What is formed after fertilization?
A zygote is formed, which is a single cell containing genetic material from both male and female parents.
