BIOLOGY
- SEED DISPERSAL
- Wind
- The flower has long anthers and styles so
that the plant can catch any pollen floating
on the wind, and release any of its own.

- Insect / mammal
- Burrs on animal fur, eats seed and then
excretes it, insect crawls into flower and
the pollen gets stuck to its body.

- The seed will float for hundreds of
miles, usually coconuts.

- PREGNANCY
- The Umbilical Cord
- Attaches the
foetus to the
placenta.
- Carries any unwanted waste
back out to the mother...
- ...And carries nutrients in

- The difference
between an
embryo and a
foetus!
- The embryo is the first ball
of cells while the foetus is
the little baby!

- DEFICIENCY DISEASES
- Vitamin C = Scurvy
- Scurvy causes bleeding
gums, loss of teeth and
then death.

- Vitamin D = Rickets
- Rickets causes your muscles
and bones to become weak and
soft.

- Iron = Anaemia
- When you dont have enough
healthy red blood cell to carry
oxygen around your body you
get anaemia. This causes lack of
energy and breath.

- Protein = Kwashiorkor
- Kwashiorkor causes
flaky skin, pot belly,
muscle loss

- GAS EXCHANGE, RESPIRATION
AND BREATHING
- Gas Exchange is the process where
oxygen is carried into the
bloodstream from the lungs and
where carbon dioxide is carried
out of the bloodstream into the
lungs.
- Breathing is inhaling and exhaling
- When you have
asthma, your
bronchioles
become inflamed
and they swell
up, mucus also
builds up.

- Respiration is where the energy
in food defuses from the
bloodstream into the every cell
in the body.
- Oxygen and glucose go into the
mitochondria and carbon dioxide
and water comes out.

- DIGESTION IN THE MOUTH
- In your saliva you have enzymes
called amylase which breaks
down starch.

- FOOD TESTS
- Starch = iodine
It will go dark
blue / black
- Fat = Ethanol It will
go milky white
- Sugar = Benedicts solution
heat up and it will go
orangy-green
- Protein = Biuret solution
It will go mauve
- Starch = iodine
It will go dark
blue / black
- Mitochondria are
the organelles
where respiration
occurs
