  1. In the female reproductive system, what is the tube that connects the ovaries to the uterus called?
    Oviduct or fallopian tube
  2. In the female reproductive system, what do the ovaries do?
    it is where the egg cell matures (produced).
  3. What is the male sex cell called?
    Sperm Cell.
  4. What is the female sex cell called?
    Egg cell or Ova.
  5. In the female reproductive system, what does the uterus or womb do?
    It is where the baby develops in pregnancy.
  6. In the female reproductive system, what is the function of the cervix?
    It is a ring of muscle at the bottom of the womb that holds the baby in place during pregnancy.
  7. What is the function of the bladder?
    It stores urine.
  8. In the male reproductive system, what is the tube inside the penis that can carry urine or semen out of the body called?
    The urethra
  9. In the male reproductive system, what is the two functions of the penis?
    • To pass urine out of the man's body.
    • To pass semen into the vagina of a woman during sexual intercourse.
  10. In the male reproductive system, what is the function of the testes?
    • Tto produce millions of male sex cells called sperm
    • To make male sex hormones, which affect the way a man's body develops.
  11. In the male reproductive system, what is the bag of skin around the testes called?
    Scrotum.
  12. In the male reproductive system, what is the function of the glands?
    To add a fluid to sperm to provide nutrients for them.
  13. In the male reproductive system, what is the tube called that connects the testes to the urethra?
    Sperm duct
  14. In the female reproductive system, what is the muscular tube that leads from the cervix to the outside of the woman's body.
    The vagina.
  15. What is Ovulation?
    When an egg is released from an ovary.
  16. What is fertilization?
    When an sperm cell meets and joins with an egg cell.
  17. What is fertilization?
    Menstruation.
  18. In the female reproductive system, what is the muscular tube that leads from the cervix to the outside of the woman's body.
    The placenta is responsible for providing oxygen and nutrients, and removing waste substances. It grows into the wall of the uterus and is joined to the foetus by the umbilical cord.
  19. How is the foetus (developing baby) protected in the uterus?
    By the amniotic fluid, a liquid contained in a bag called the amnion.
  20. What does DNA do?
    DNA is large and complex molecules. They carry the genetic code that determines the characteristics of a living thing.
  21. What is a gene?
    A gene is a short section of DNA. Some characteristics, such as eye colour and the shape of the earlobe, are controlled by a single gene.
  22. What is an allele?
    • Different forms of the same gene are called alleles.
    • The gene for eye colour has an allele for blue eye colour and an allele for brown eye colour.
  23. What is a dominant allele?
    The characteristic controlled by a dominant allele develops if the allele is present on one or both chromosomes in a pair
  24. What is a recessive allele?
    The characteristic controlled by a recessive allele develops only if the allele is present on both chromosomes in a pair
  25. What are chromosomes?
    Rod shaped bodies found in the nucleus of cells that contain genetic information (DNA)
