Fill in the facts according to your groups. Everyone has to post one fact/diagram/link to another webpage.

Group 1 A woman’s reproductive system is where her body stores, releases and nurtures the egg cells One egg cell is released every monthly by one of the ovaries. A man’s reproductive system is where his testes produce sperm cells that fuses with the egg. The testes release a hormone that controls the development of sperm. The womb is where the fetus develop into a new-born baby. Male sperm are significantly smaller than the female egg. Group 2 -A man's reproductive system is where his body creates the sperm cells that combine with a female egg cell to create a new human life. -The reproductive system is a system of organs within an organism which __#|work__ together for the purpose of reproction. -Only one sperm can fertilise one egg Group 3 -the sperm cell fuses with an egg cell to fertilise the egg. -the womb recieves the fertilised egg and supports the developing baby in the mother's body.

Group 4 -Food is provided for the foetus in the mother 's womb through the umbilical cord. - The major organs of the reproductive system includes, the external genitalia (penis and vulva) as well as a number of internal organs including the gamete producing gonads (testicles and ovaries). -The testes release a hormone that controls the development of sperm - During intercourse, the interaction between the male and female reproductive systems results in fertilisation of the woman's ovum by the man's sperm, which after a gestation period is followed by childbirth. - Pregnancy is the period of time during which the foetus develops, dividing via mitosis inside the female.

Group 5 -Fertilisation brings together 23 chromosomes from the male and 23 chromosomes from the female, resulting in the formation of a fertilised egg cell with 46 chromosomes. -The foetus developing inside the womb of the female is fed through the fallopian tube. -The egg produced by the ovary of the female's reproductive system is fertilised by the sperm produced by the testesof the male's reproductive system. -The number of sperm cells produced varies with the size of the testicles, but averages 85 million sperm per day per testicle.

Group 6 -Each ovary contains on average hundreds of egg cells. -The reproductive system or genital system is a system of organs within an organism which work together for the purpose of reproduction. -Human beings carry out sexual reproduction and reproduce to ensure continuity of their own kind. -Each ovary releases mature eggs into an oviduct or Fallopian tube.

Group 7 -The female reproductive system have 2 fuctions. The first is to produce egg cells, and the second is to protect and nourish the offspring until birth. -A male have more than a hundred sperms and only one can fertilize an egg at a time.

Group 8 - The ovaries of the female reproductive system produces eggs. - The ovaries are either oval or almond shaped and they are about the size of an olive. -The sperms in Male Reproductive System only survive in warm environments - The womb in the female reproductive system stores the eggs. - Only one sperm survives and fuses with the egg. The rest dies. - Male sperm are significantly smaller than the female egg. Group 9 - The female reproductive system produce egg cells and protects, nourishes the offspring until birth. - The ovaries release an ovum about every 28 days. - The sperm from the male fuses with the egg from the female. - Characteristics can be passed down by parents to offspring. - There are two types of fertilisations, internal fertilisation and external fertilisation. - Internal fertilisation takes place in the female's womb while external fertilisation takes place outside the mother's womb. - The disadvantage of external fertilisation is that the sperms released by the male animal may not find the eggs and not all will be fertilised. -The advantage of internal fertilliastion is that the parent canprotect the egg while the egg that is laid is exposed to the dangers of the environment. -A healthy female produce an egg cell every month -The male has testis and pennis parts. -The female reproductive system has ovary,womb,vagina and fallopian tube.
