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.
Water
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
Mitochondria are
the organelles
where respiration
occurs
