This would indicate that less photosynthesis
would take place, as carbon dioxide is one of the 2 products required
by a green-plant for photosynthesis to take place.
My reasons for believing my results are reliable & accurate are
firstly, they agree with the theory behind the rate of photosynthesis
when light intensity is increased, secondly the result which I gained
compared accurately to my prediction, which was well thought out
before it was made, and finally the results I gained for my final
experiment differed so much to the results of my preliminary procedure
which was very inaccurate.
our topic right now, namely photosynthesis,is arguably one of the most important chemical reactions occurring on theplanet. Let's see why.
I think this because the plant may use up all of the carbon dioxide (Sodium hydro carbonate) and the plant can have as much light as it needs but if it does not have any carbon dioxide it will not be able to photosynthesise....

The chemical equation of photosynthesis is: [IMAGE]6CO2 + 6H20 C6 H12 O6 + 6O2 it has been proven many times that plants need light to be able to photosynthesize , so you can say that without light the plant would neither photosynthesize or survive....
This process is also affected by the temperature surrounding the plant (the species of plant we experimented with, pond weed, photosynthesised best at around 20 degrees centigrade.) Light, temperature & CO2 are known as limiting factors, and each is as important as the next in photosynthes...
Furthermore, I predict that if the light intensity increases, the rate of photosynthesis will increase at a proportional rate and more oxygen will be produced and therefore the oxygen levels will increase.
My reason for believing this
is that as mentioned previously, light is one of the limiting factors
required for photosynthesis, and by lowering the amount of light
available to the plant, I will be decreasing the rate at which the
process of photosynthesis takes place in the plant.
providing the plant with a greater intensity of light, I will be
enabling the plants' process of photosynthesis to take place more
intensively, as the factor required (in this case light) is available
at a greater quantity.
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.
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.
Effectively this shows
that if more of these limiting factors can be used by a larger sample
compared to a smaller sample, then the rate or amount at which the
products of photosynthesis are given off will be at a higher level
If we had conducted the
experiment with the surrounding temperature at 30 degrees then we may
have found that the rate of photosynthesis would have been very low,
or even that photosynthesis within the pond weed was non existent.
In the case of
the pond weed if they enzymes within the plant became denatured then
it would become unable to photosynthesise, as well as not being able
to complete other functions.
