(a) complete the equation for photosynthesis.
light
carbon dioxide + water –
water chlorophyll
glucose
sc
+ oxyger
(b) the pondweed was placed in a test tube of water at 10°c.
the number of bubbles of gas produced by the pondweed in three minutes was recorded.
this was repeated with water at different temperatures.
the light intensity was kept constant for each temperature.
(i) state why the light intensity absorbed by the pondweed is not the same as
the light intensity measured by the light meter.
(ii) give two ways of improving this investigation.
