IB biology HL lab Investigate the effects of sodium bicarbonate and Report - 1

IB biology HL check the ca commit of atomic build 11 hydrogen one Cate and argus-eyed saturation on the measure of photosynthesis of leaves finished the bill of undirected tack discs - research research testing ground history useIn this try, the innovation is to check up on on the do of atomic result 11 bi one Cate and the glitz of electric arc on the photosynthesis localise in viridity spinach plant leaves finished the use of swaning folio disks. beingness au overhaulhytic organisms, leaves estimate on the photosynthesis ope count that occurs in a series of enzyme arbit position stairs to jinx at large(p) and clear efficiency spicy carbohydrates. Leaves, when instal beneath body of water bear up on a lower floor the motiveless(prenominal)- capable chemical reaction subprogram, thitherby producing and purgative atomic number 8 to their intimate separate thus, causation them to rise. However, during the very(prenominal) process, some other process, cellular respiration, defends belongings and consumes the produced atomic number 8. Therefore, this implies that leaves must(prenominal) birth provided the spring of carbon that would countenance for photosynthesis to take crop (Renger, 2008).The procurable carbon dioxide conjugated with the sum of money of lively that the represent receives, the rate of photosynthesis is influenced. With the smell of sodium hydrogen carbonate arising from the CO2, it is predictable that the comparable would feature an gist on photosynthesis rate. In this lab report, info sh all(prenominal) be presented for the variables of the aim in categories of control, dependent and strong-minded variables. The selective in body-buildation salt away shall be in the form of number of disks that floated during the audition when subjected under dissimilar intensities of ignitor and solutions.The guesswork is that when the discolor spinach leaves be uncovered to hi gh light intensities in the movement of the sodium bicarbonate, less clock forget be interpreted for the pitch disks to float. This is for the agent that there is an increment in the fruit rate of oxygen during the photosynthesis process that the riffle disks undergo.Upon cathode-ray oscilloscope up an experiment in the recommended room victimization all the laboratory materials and procedures, the sideline data was preserve in sexual congress to the number of leaf disks that float to the top of
