This can be seen with the upward sloping curve. On the other hand, in figure 2, the leaves are sinking gradually due to absence of photosynthesis as a result of no light. This can be seen from the down sloping curve.
In the table 2 above light is present hence photosynthesis will take place but at higher rate with 0.4% of bicarbonate which produces more carbon (IV) oxide than 0.2% concentration hence the observed higher rate of floating in 0.4%. However at a certain time, rate of photosynthesis reaches optimum point indicated by 10 floats which is the maximum.
The following conclusive results would be made out of this experiment.The leaves disks are able to undertake photosynthesis in water as they use dissolved carbon (IV) oxide and oxygen also for respiration. This is why the experiment was able to be successful in water. It is also worth to note that rate of photosynthesis is influenced by carbon (IV) oxide supply as indicated by the higher rates in floats by 0.4% of bicarbonate more than 0.2%. It can also be noted that rate of leaves disks were higher in the presence of light than darkness from the observations above proving that light is necessity for photosynthesis holding other factors ...Download file to see next pagesRead More

Effects of Green and Blue Light on the Rate of Photosynthesis
Photosynthesis is the process through which green plants, algae, and cyanobacteria convert the sun’s energy into chemical bond energy of organic molecules that it consumes as food. This paper covers two experiments on photosynthesis; the first one investigates whether a positive rate of net photosynthesis depends on light levels.

Report on photosynthesis lab
Our results indicate that apparent photosynthetic rate increases with temperature. We discuss the possible reasons for the observed pattern and discuss the implications that the relation may have for plant growth and productivity. Among several environmental variables, temperature has been known to strongly influence photosynthetic rate of plants (Blackman, 1905).

Photosynthesis
Photosynthesis relates to the process through which green plants and other specific organisms use sunlight in synthesizing carbohydrates from water and carbon dioxide. The process occurs in three imperative stages including harnessing sunlight energy, synthesizing NADPH and ATP using energy harnessed, with the last step being Calvin cycle involving CO2 fixation

With the assumption that the rate of photosynthesis as manifested by CO2 consumption would be inversely related to the received light wavelength, drops in CO2 recorded and data calculated. Green wavelength having the lowest rate of photosynthesis was the only data adhering to what we had predicted.
