Summary
Reproduction in humans involves sexual reproduction, where a male and female mate to produce offspring, passing on characteristics such as earlobe type and blood type. Sexual Reproduction — requires a male and female to mate, enabling the survival of humans. Example: Humans inherit traits like earlobe type from their parents.
- Female Reproductive Organ — includes the ovary, vagina, and womb, which produce eggs. Example: The ovary releases an egg during the reproductive cycle.
- Male Reproductive Organ — includes the testis and penis, which produce sperm. Example: The testis produces sperm necessary for fertilisation.
- Fertilisation — the fusion of sperm and egg to form a fertilised egg. Example: Fertilisation occurs in the female's womb, leading to the development of a baby.
- Human Life — begins with a nine-month journey where the fertilised egg grows into a baby. Example: The developing baby receives nutrients through the umbilical cord.
