But this only happens up to a certain point. Create a vacuum in the syringe by covering the tip of the syringe with your finger while drawing back on the plunger.
Remember that this operation has to be performed with all possible accuracy. Furthermore, I hypothesised that if the light intensity increases, the rate of photosynthesis will increase at a proportional rate until a certain level is reached, and the rate of increase will then go down.
Avoid wax-coated leaves; try using leaves from bagged spinach salad. Place ml of 0. The remaining part is just as important as the practical phase of work.
You should not only analyze all the processes, but also give the critical evaluation of your own work. Experiment with light intensity as well be sure to account for differences in heat.
IntroductionPhotosynthesis occurs only in the presence of light, and takes place in the chloroplasts of green plant cells. There are many factors, which affect the rate of photosynthesis, including light intensity, temperature and carbon dioxide concentration.
Particularly, we are going to tell about some basic elements of your photosynthesis coursework. For detailed graph, see separate sheet. Replace the plunger into the barrel leaving only a small amount air, but do not crush the leaf discs.
Improvements could have been made as I have stated, mainly by simply increasing the time taken. My idea that the rate of photosynthesis would increase with light intensity was comprehensively backed up by my results.
Studying the photosynthesis process also has a great number of advantages. A scientific paper found at http: Among the most important of them we can separate the following theses: As I raise the light level, by moving the lamp closer in this case, the rate of photosynthesis increases also.The Effect Of Temperature On Rate Of Photosynthesis Of Pondweed Plant - Coursework Example Nobody downloaded yet Extract of sample The Effect Of Temperature On Rate Of Photosynthesis Of Pondweed Plant.
Coursework on photosynthesis “Investigating link between light intensity and photosynthesis” Aleksandra Kozielska, IB Introduction Plants produce oxygen. Biology Coursework: Rate of Photosynthesis Aim To investigate a factor that affects the rate of photosynthesis.

In photosynthesis, a plant takes carbon dioxide from the air and water from the soil and uses the light from sunlight to turn them into food.
Photosynthesis occurs only in the presence of light, and takes place in the chloroplasts of green plant cells.1/5(1). GCSE Biology - Photosynthesis Coursework my experiment, I did a preliminary investigation in which I recorded the number of bubbles of oxygen given off in a given time at various light intensities.
To alter the light intensity, I placed a lamp at .Download
