Q

What is the job of the MALE reproductive system?

A

The job of the male reproductive system is to MAKE LARGE NUMBERS OF SPERM and deliver these inside the body of the FEMALE.

Q

What is the job of the FEMALE reproductive system?

A

The female’s role in reproduction is a bit more complex:

  1. Her body PRODUCES the female sex cells (EGGS)
  2. RECEIVES the SPERM from the male
  3. FERTILISATION takes place in the female
  4. Female provide PROTECTION for the developing baby

Q

What are the SEX CELLS?

A

The Sex Cells (or GAMETES) are:

  1. Sperm (Male)
  2. Egg (Female)
17
Q

Can you describe the FERTILISATION process?

A
  1. Fertilisation occurs in the OVIDUCTS
  2. One sperm PENETRATES the egg
  3. A MEMBRANE forms around the egg to PREVENT other sperms entering it.
  4. Fertilisation is when SPERM NUCLEUS and the EGG NUCLEUS fuse together to form the ZYGOTE.
18
Q

Can you describe the process IMMEDIATELY AFTER FERTILISATION ?

A
  1. Once fertilisation takes place, the zygote begins to DIVIDE
  2. One cell becomes 2, which then divides to become four.
  3. This ball of calls is known as the EMBRYO.
  4. The embryo travels to the UTERUS and implants in the thickest LINING of the UTERUS.
  5. Here the FERTILISED EGG will receive all the NUTRIENTS it needs to GROW.
19
Q

What are the main parts of the FERTILISATION process?

A
20
Q

Can you describe the DEVELOPMENT OF THE EMBRYO process?

A
  1. Once the embryo implants in the wall of the uterus, it has to receive NUTRIENTS and OXYGEN from the mother.
  2. The nutrients and oxygen are needed for the embryo to GROW and DEVELOP.
  3. This role is carried out by the PLACENTA.
21
Q

Can you label the main parts of the PLACENTA?

A
22
Q

What is a PLACENTA?

A

The placenta is the embryo’s organ of: NOURISHMENT, GASEOUS EXCHANGE, and EXCRETION:

23
Q

What is the role of the PLACENTA?

A

The placenta provides:
.

  1. NOURISHMENT: The placenta is an organ which allows the blood supplies of the mother and the embryo to come very close, but not in contact.
  2. GASEOUS EXCHANGE: Oxygen and Nutrients pass from the mother’s blood into the embryo’s blood, which then flows along the Umbilical Cord to the developing embryo.
  3. EXCRETION: Carbon Dioxide (CO2) and other Waste (e.g. urea) are returned to the mother’s blood in the opposite direction.
24
Q

What is the AMNIOTIC SAC?

A
  1. Inside the uterus, the developing baby is enclosed in a sac - called the AMNIOTIC SAC
  2. This is filled with AMNIOTIC FLUID
  3. which CUSHIONS and PROTECTS the baby from sudden SHOCKS and BUMPS.
25
Q

Can you label the main parts of the AMNIOTIC SAC ?

A
26
Q

What is the function of: AMNIOTIC SAC

A

STRUCTURE that contains the AMNIOTIC FLUID and developing EMBRYO.

27
Q

What is the function of: AMNIOTIC FLUID

A

Fluid which CUSHIONS and PROTECTS and developing embryo from sudden SHOCKS and BUMPS.

28
Q

What is the function of: UMBILICAL CORD

A

Cord which attaches the developing EMBRYO to the PLACENTA

29
Q

What is the function of: PLACENTA

A

Organ which allows EXCHANGE of MATERIALS between the MOTHER and EMBRYO.

30
Q

What HARMFUL SUBSTANCES taken by the mother can have severe consequences for the development and safety of the baby?

A
  1. Harmful substances such as ALCOHOL, NICOTINE (from smoking) and other DRUGS can also CROSS the PLACENTA.
  2. These can have HARMFUL effects on the development of the embryo
  3. May lead to serious PHYSICAL and MENTAL ABNORMALITIES.

32
Q

What type of graph is:

A

A

34
Q

What is VARIATION?

A

Variation is the term used to describe the DIFFERENCES between members of a SPECIES which are NOT DUE to PHYSICAL ACCIDENT.

35
Q

What are the two broad CATEGORIES of Variation?

A
36
Q

What are examples of VARIATION?

A
37
Q

What are the four types of FINGER PRINTS?

A
38
Q

A female frog released 1000 eggs, 750 are fertilised
Of those fertilise, 250 were eaten
After hatching, a further 400 tadpoles died
.
What percentage survived?
