De-starching a
plant leaving
:
it in the dark for 48 hours to remove starch
Control experiment experiment to
something caused the reactant
is
by only
:
an
prove
Oxygen by-product because it also used for respiration
Usually there is more than needed it diffuses into the atmosphere
·
is a is . so
Investigating the effect of light :
covering part of the leaf with black
paper , leaving it in the sun
, testing for starch
Investigating the effect of CO2 placing plants
: into container o n e with
,
a CO2 absorber Ce .

Sodium hydroxide) ,
carry
out starch test
Investigating the effect of chlorophyll : use plant with vegitated leaves (some parts don't have chlorophyll) ,
starch test
Products of photosynthesis Investigating the rate of photosynthesis :
·
Glucose used as a source of respiration
-
Changing temperature (maintaining with hot plate water bath)
energy
is in or
Converting glucose Changing light
·
transport intensity (distance to light source
-
into s u cros e for
Converting glucose into starch
storage
·
:
for
↳
lipids for an
energy store in seeds
↳
Cellulose to make cell walls
↳ Amino
acids to make proteins when combined with
nitrogen & other mineral ions absorbed by roots -
lots of Carbon
Limiting Factor :
Something present in the environment in such
short that it restricts life processes
supply
·
Water not considered factor because the amount needed amount of water transpired from
is a
limiting is
relatively small compared to the
a plant .
There is
hardly ever a situation where there's not enough water for photosynthesis
Temperature :
As temperature the rate of
increases , photosynthesis increases as the reaction is
enzyme
controlled
After a certain point ,
the
enzymes begin
to denature and the rate of
photosynthesis decreases
