State that photosynthesis involves the
conversion of light energy into chemical
energy.
3.8.2
State that light from the Sun is composed of
a range of wavelengths (colours).
3.8.3
State that chlorophyll is the main
photosynthetic pigment.
3.8.4
Outline the differences in absorption of
red, blue and green light by chlorophyll.
8.2.7
Explain the relationship between the action
spectrum and the absorption spectrum of
photosynthetic pigments in green plants.
Light Dependent Reaction
3.8.5
State that light energy is used to produce
ATP, and to split water molecules
(photolysis) to form oxygen and hydrogen.
8.2.2
State that photosynthesis consists of
light-dependent and light-independent
reactions.
8.2.3
Explain the light-dependent reactions.
8.2.4
Explain photophosphorylation in terms of
chemiosmosis.
Light Independent Reaction - Calvin Cycle
3.8.6
State that ATP and hydrogen (derived from
the photolysis of water) are used to fix
carbon dioxide to make organic molecules.
8.2.5
Explain the light-independent reactions.
Overall
3.8.7
Explain that the rate of photosynthesis can
be measured directly by the production of
oxygen or the uptake of carbon dioxide, or
indirectly by an increase in biomass.
3.8.8
Outline the effects of temperature, light
intensity and carbon dioxide concentration
on the rate of photosynthesis.
8.2.1
Draw and label a diagram showing the
structure of a chloroplast as seen in
electron micrographs.
8.2.6
Explain the relationship between the
structure of the chloroplast and its
function.
8.2.8
Explain the concept of limiting factors in
photosynthesis, with reference to light
intensity, temperature and concentration of
carbon dioxide.
