Investigation To Find The Effect Of Temperature On The Rate Of Photosynthesis Of Elodea

Hypothesis

I believe that as the temperature rises, the rate of photosynthesis will also increase. That is until the plant reaches its optimum temperature and then the rate of photosynthesis will decrease.

Photosynthesis is the process necessary for plants as this is how they obtain their food. The formula for this process is- 6CO2 + 6H2O ?6H1206 + 602. The rate of photosynthesis are affected by these factors: concentration of carbon dioxide, light intensity and temperature.If one of these factors increase, the rate of photosynthesis will increase but only to a certain point. The rate of photosynthesis could still increase but not because of an increase in that same factor. Another factor has to increase for the rate to increase. The factor that restricts the other two factors from increasing the rate of photosynthesis is called the limiting factor.

For glucose to be made in photosynthesis, water is split into hydrogen and oxygen molecules by the energy absorbed from the sun. The hydrogen then has to combine with the carbon dioxide to produce glucose. If this was left on its own,
