When photosynthesis takes place, plants use the suns energy to combine carbon dioxide from the air with water from the soil to create glucose (a carbohydrate)....

 Graph: Shows the effect of light intensity on the process of photosynthesis in an aquatic plant.



Reason 1

When the green plant is provided with a higher concentration of CO2 in
the environment it is photosynthesising in, the rate of photosynthesis
conducted by the plant will be higher - the availability of one of the
limiting factors was higher.

LabBench Activity Plant Pigments and Photosynthesis

Aim To see whether light effects the rate of Photosynthesis in plants or not....

Variables: The variables that might affect the rate of photosynthesis in this experiment are: Temperature: When the temperature rises so does the rate of photosynthesis; this is because as the temperature around the plant rises the enzymes controlling photosynthesis inside the chloroplasts heat up and start moving around faster, the fast moving molecules collide with other fast moving enzymes causing them to react....

From this it can be said that the
more light a plant is provided with (the more of a limiting factor is
takes in) then the higher the rate at which the pond weed, or any
plant, will give off a product of photosynthesis i.e.

And as both methods (finding starch/ measuring
oxygen given off by the plant) show that photosynthesis is taking
place, I chose to measure the rate of oxygen produced.
