The purpose of the male reproductive system is to produce and deliver sperms. Sperm is the male gamete or sex cell. Sperm production is influenced by the hormone testosterone, which is produced in the testis. Sperms are also produced in the testis. For further explanation.

Female Reproductive System
The purpose of the female reproductive system is to produce eggs and provide a safe nutritious place for the embryo to develop. Egg maturation and release is influenced by the hormone estrogen, and estrogen is produced by the ovaries. The egg is the female sex cell. For further explanation.

Ovaries- produce eggs.
Ovulation- is the process where the ovary releases the egg.
Fallopian tubes- also known as oviduct is the site of fertilization or is where the sperm meets the egg.
Fertilization- is the union of sperm and egg.
_______________________________________________________
After the sperm enters the egg, the newly formed cell or the zygote travels to the uterus for implantation.
Zygote- is a fertilized egg

Uterus- is a structure in the female reproductive system that provides a safe nutritious environment for the embryo or fetus to develop.
Placenta- is the site of exchange between the fetus and the mother. For example, nutrients and oxygen go from the mother to the fetus and waste products and CO2 go from the fetus to the mother.
Sexual reproduction requires two parents and the offspring are not identical, except in the case of identical twins.
Asexual reproduction requires only one parent and the offspring are genetically identical to the parent. ( binary fission, fragmentation and budding are other types of asexual reproduction and cloning.
How are sex cells different from body cells?
- sex cells have half the number of chromosomes, while body cells have a full set of chromosomes.
What type of cell division produce sex cells?
- meiosis produces the sex cells or gametes (the sperms or the eggs).
In what structure in the female reproductive system does fertilization occur?
- Fertilization occurs in the fallopian tube or oviduct. Fertilization is when the sperm enters the egg.
List two substances that can harm a developing fetus.
- Two substances that can harm fetus are drugs and alcohol.
What is the role of the placenta?
The placenta allows material to be exchanged between the fetus and the mother. For example: oxygen goes from the mother to the baby, while carbon dioxide goes from the baby to the mother
