Photosynthesis - Lab Report Example

Download file to see previous pages In table 1 above figure 1, the rate leaves floats with time indicating that photosynthesis is taking place in the presence of lit. 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
