This KS3 Science quiz takes a look at reproduction. If egg and sperm are mentioned in the same breath, chances are the conversation is about reproduction. Reproduction allows all living things to produce more of their kind. The reproductive system is a system of organs within an organism which work together for the purpose of reproduction. Humans are mammals and therefore have similar reproductive organs to other mammals like cats, elephants and polar bears. The way the reproductive system of each species works is slightly different to all other species, so at KS3, we focus on how our own reproductive system functions.

The main organs of the female human reproductive system are the ovaries, oviducts (fallopian tubes), uterus (commonly called the womb) and the vagina.

Once a month, changes in the hormones in a woman's body causes an egg to be released from the ovaries. At the same time, the lining of the uterus thickens. When the egg reaches the uterus, if it has been fertilised, it will embed in the uterus lining and develop into a baby. If it is not fertilised, it will pass out of the body through the vagina, together with the lining of the uterus and the whole cycle begins again.

Which of the following is NOT part of the female reproductive system?

[ ]	Ovary
[ ]	Testes
[ ]	Uterus
[ ]	Vagina

Which of the following is NOT part of the male reproductive system?

[ ]	Oviduct
[ ]	Penis
[ ]	Scrotum
[ ]	Sperm duct

In the female reproductive system, an egg is released monthly from which organ?

[ ]	An ovary
[ ]	The oviduct
[ ]	The uterus
[ ]	The vagina

Fertilisation of an egg occurs in:

[ ]	the ovary
[ ]	the oviduct
[ ]	the uterus
[ ]	the vagina

The life support system for a baby is in:

[ ]	the ovary
[ ]	the oviduct
[ ]	the uterus
[ ]	the vagina

In the male reproductive system sperm are produced:

[ ]	in the penis
[ ]	in the sperm duct
[ ]	in the testes
[ ]	in the urethra

In the male reproductive system the urethra carries:

[ ]	just sperm
[ ]	just urine
[ ]	sperm or urine
[ ]	neither sperm nor urine

When sexual intercourse takes place:

[ ]	sperm are released into the ovary
[ ]	sperm are released into the oviduct
[ ]	sperm are released into the uterus
[ ]	sperm are released into the vagina

Choose the correct order for the changes in the uterus wall which occur every month in a fertile woman.

[ ]	Egg is released, uterus stays thick, lining breaks down, uterus wall thickens
[ ]	Egg is released, uterus wall thickens, stays thick, lining breaks down
[ ]	Uterus lining thickens, stays thick, lining breaks down, egg is released
[ ]	Uterus wall thickens, egg is released, uterus lining stays thick, uterus lining breaks down

10.

Choose the correct order leading to a fertilised egg attaching itself to the uterus wall.

[ ]	Cell division, ovulation, fertilisation, implantation
[ ]	Fertilisation, cell division, implantation, ovulation
[ ]	Implantation, cell division, ovulation, fertilisation
[ ]	Ovulation, fertilisation, cell division, implantation

Science Quiz - Reproduction 01 (Answers)

Which of the following is NOT part of the female reproductive system?

[ ]	Ovary
[x]	Testes
[ ]	Uterus
[ ]	Vagina

These are part of the male reproductive system

Which of the following is NOT part of the male reproductive system?

[x]	Oviduct
[ ]	Penis
[ ]	Scrotum
[ ]	Sperm duct

Eggs pass through this organ from the ovary to the uterus

In the female reproductive system, an egg is released monthly from which organ?

[x]	An ovary
[ ]	The oviduct
[ ]	The uterus
[ ]	The vagina

A female human is born with a limited supply of eggs

Fertilisation of an egg occurs in:

[ ]	the ovary
[x]	the oviduct
[ ]	the uterus
[ ]	the vagina

The oviduct is also called the fallopian tube

The life support system for a baby is in:

[ ]	the ovary
[ ]	the oviduct
[x]	the uterus
[ ]	the vagina

It is called the placenta

In the male reproductive system sperm are produced:

[ ]	in the penis
[ ]	in the sperm duct
[x]	in the testes
[ ]	in the urethra

Sperm cells are very tiny compared to an egg cell but they have a sort of tail that enables them to travel from the vagina to the oviduct

In the male reproductive system the urethra carries:

[ ]	just sperm
[ ]	just urine
[x]	sperm or urine
[ ]	neither sperm nor urine

The urethra carries sperm or urine, but not at the same time

When sexual intercourse takes place:

[ ]	sperm are released into the ovary
[ ]	sperm are released into the oviduct
[ ]	sperm are released into the uterus
[x]	sperm are released into the vagina

From there, they 'swim' through the uterus into the oviducts. Most of them die on the way and only one can fertilise an egg cell

Choose the correct order for the changes in the uterus wall which occur every month in a fertile woman.

[ ]	Egg is released, uterus stays thick, lining breaks down, uterus wall thickens
[ ]	Egg is released, uterus wall thickens, stays thick, lining breaks down
[ ]	Uterus lining thickens, stays thick, lining breaks down, egg is released
[x]	Uterus wall thickens, egg is released, uterus lining stays thick, uterus lining breaks down

This is controlled by hormones that circulate in the bloodstream

10.

Choose the correct order leading to a fertilised egg attaching itself to the uterus wall.

[ ]	Cell division, ovulation, fertilisation, implantation
[ ]	Fertilisation, cell division, implantation, ovulation
[ ]	Implantation, cell division, ovulation, fertilisation
[x]	Ovulation, fertilisation, cell division, implantation
