What is the male sex cell called in humans?

• Egg

• Pollen

• Sperm

• Tails

Multiple Choice

Where does the baby develop inside a woman?

• Stomach

• Uterus (womb)

• Vagina

• Intestines

Male sperm cells are much smaller than female egg cells

All of these features help the sperm and egg cells to carry out their jobs!

Sperm Cells

Tail: Helps the sperm to swim

Shape: Streamlined

Acrosome: Contains enzymes

Nucleus: Contains father's DNA

Mitochondria: Provide energy

Egg Cells

Nucleus: Contain's mother's DNA

Jelly coating: Protection

Large size: Sperm can find it easily

Reproductive Systems

​Around the room are fully labelled diagrams of reproductive organs.

​

​In groups of three, nominate one person to write.

​

​One other person will have 30 seconds to look at the labelled diagram and remember as much as possible.

​

Return to your desk and tell your scribe, who will write it down​

​

Then the second person will go to look.​

Female Reproductive System

The female reproductive system is very complex

It needs to provide a safe place for a baby to develop

Female Reproductive System

Eggs are released from the ovary and travel along the oviduct (fallopian tube) to reach the uterus

If sperm are swimming up from the vagina and meets the egg, it will fertilise the egg

The egg will implant in the uterus (womb) and a baby will develop

The cervix will hold the baby inside the uterus as it grows

Male Reproductive System

The male reproductive system is responsible for producing sperm cells

Male Reproductive System

Sperm cells are produced in the testes located in the scrotum.

They travel up the sperm duct and down the urethra that runs through the middle of the penis to be released from the body.

The prostate gland adds extra fluid to the sperm cells to make it easier for them to swim.

The foreskin protects the head of the penis.

Now how do you feel about this topic?

• I understand it!

• I don't really get it

• There are too many new words!

• I don't get it at all!

THINK: How many sperm cells do you think are released from the testes at a time?

Open Ended

How many sperm cells do you think are released from the testes at one time? Why do you think that is?

Wow!

Between 80-300 million sperm cells are released at one time!

Most of these will die though and will not reach an egg cell to fertilise it!

So many are released to increase the chances of it meeting an egg cell

Do you have any questions?

Be honest, but keep it sensible!
