Pupils should be
taught:
|
1. Life processes and cell activity
|
a
that many animals and plants have organs that enable life
processes, eg reproduction, to take place;
|
b
that animals and plants are made up of cells;
|
c
the functions of the cell membrane, cytoplasm and nucleus in plant
and animal cells;
|
d
the functions of chloroplasts and cell walls in plant cells;
|
e
ways in which some cells, including ciliated epithelial cells,
sperm, ova, palisade cells and root hair cells, are adapted to
their functions.
|
2. Humans as organisms
|
|
nutrition
|
a
that balanced diets contain carbohydrates, proteins, fats,
minerals, vitamins, fibre and water;
|
b
some sources of the main food components in the diet;
|
c
that food is used as a fuel during respiration to maintain the
body`s activity and as a raw material for growth and repair;
|
d
the principles of digestion, including the role of enzymes;
|
e
that the products of digestion are absorbed and waste material is
egested;
|
circulation
|
f
how blood acts as a transport medium and about the exchange of
substances at the capillaries;
|
movement
|
g
the role of the skeleton, joints and muscles in movement;
|
h
the principle of antagonistic muscle pairs, eg biceps and
triceps;
|
reproduction
|
i
about the physical and emotional changes that take place during
adolescence;
|
j
the human reproductive system, including the menstrual cycle and
fertilisation;
|
k
how the foetus develops in the uterus, including the role of the
placenta;
|
breathing
|
l
how lung structure enables gas exchange to take place;
|
m
how smoking affects lung structure and gas exchange;
|
respiration
|
n
that aerobic respiration involves the reaction in cells between
oxygen and food used as a fuel;
|
o
that during aerobic respiration glucose is broken down to carbon
dioxide and water;
|
p
to summarise aerobic respiration in a word equation;
|
|
Pupils should be taught:
|
health
|
q
that the abuse of alcohol, solvents and other drugs affects health;
|
r
that bacteria and viruses can affect health;
|
s
that the body`s natural defences may be enhanced by immunisation
and medicines.
|
3. Green plants as organisms
|
|
nutrition and growth
|
a
that photosynthesis produces biomass and oxygen;
|
b
that plants need carbon dioxide, water and light for
photosynthesis;
|
c
to summarise photosynthesis in a word equation;
|
d
that nitrogen and other elements in addition to carbon, oxygen and
hydrogen are required for plant growth;
|
e
that root hairs absorb water and minerals from the soil;
|
reproduction
|
f
how sexual reproduction occurs in flowering plants, including
fertilisation and seed formation;
|
respiration
|
g
that plants carry out aerobic respiration.
|
4. Variation, classification and inheritance
|
|
variation
|
a
that there is variation within species and between species;
|
b
that variation within a species can have both environmental and
inherited causes;
|
classification
|
c
how keys can be used to identify animals and plants;
|
d
to classify living things into the major taxonomic groups;
|
inheritance
|
e
that selective breeding can lead to new varieties.
|
5. Living things in their environment
|
|
Adaptation
|
a
that different habitats support different plants and animals;
|
b
how some organisms are adapted to survive daily and seasonal
changes in their habitats, eg light intensity, temperature;
|
feeding relationships
|
c
how food chains may be quantified using pyramids of numbers;
|
d
that in food webs there are several food chains with species in
common;
|
e
how toxic materials may accumulate in food chains;
|
competition
|
f
factors affecting the size of populations, including predation and
competition for resources;
|
g
that organisms successfully competing in their environment
contribute relatively more offspring to the next generation.
