1.

A limiting factor is

the factor in shortest supply that restricts the rate of a process
any factor affecting a process
a factor that is always light
a factor that cannot be changed
2.

At low light intensity the rate of photosynthesis is limited by

carbon dioxide concentration
temperature
light intensity
chlorophyll
3.

At high light intensity and warm temperature, the rate of photosynthesis in a field crop is most likely limited by

carbon dioxide concentration
light intensity
water
oxygen
4.

Temperature affects mainly the

light-dependent stage
absorption of light
photolysis of water
light-independent stage, because it is controlled by enzymes
5.

In a glasshouse, growers increase yield by

lowering carbon dioxide concentration
reducing light
raising carbon dioxide concentration, light and temperature to optimum values
lowering temperature to 0 °C
6.

A redox indicator such as DCPIP can be used to investigate the light-dependent stage because it

gives off oxygen
absorbs carbon dioxide
is decolourised when it accepts electrons from the chloroplasts
is a pigment
7.

Aquatic plants such as Elodea are useful for measuring the rate of photosynthesis because

they have no chloroplasts
they do not respire
they need no light
the oxygen produced can be collected and measured
8.

When light intensity is suddenly reduced, the concentration of GP in the chloroplast

falls immediately
rises, because it is no longer reduced to TP
stays the same
falls to zero
9.

In an experiment on light intensity, the distance d of a lamp is varied. Light intensity is proportional to

d
d²
1/d
1/d²
10.

Hydrogencarbonate solution is added to water containing an aquatic plant to

supply oxygen
absorb light
supply carbon dioxide
lower the temperature
