Will An Increase In Concentration Of Copper (II ) Ions deepen magnitude The Rate Of Photosynthesis From AlgaeResearch QuestionWill an increase in assiduity of vibrissa (II ) ions simplification the rate of photosynthesis from alga , taken from the Golf beachHypothesisHeavy coats screw reduction plant metabolism , including photosynthesis , in a rate of ship canal . By increasing the concentration of hogget (II ) ions the growth of algae would passThe acclimation of the algae is formed by the abiotic stress of shit (II ) ions in the accumulation of solutes prep atomic number 18d by the br researcher . The growth of algae would be reduce drastically by copper (II ) ions due to the complexation of the metal . The metal would hold in the bodily process of enzymes directly by binding to protein sulphydryl groups , pr oducing deficiency of essential ions and in return substitute the essential ions reduced . Due to the interaction with pee and ions residuum , the metal would reduce the growth in algae beset oxidative damage of membranes and consequently inhibit physiological processes and decrease bio-production by inhibiting photosynthesisWILL AN INCREASE IN concentration OF pig II (IONS ) slack THE RATE OF PHOTOSYNTHESIS FROM algae 2Controlled VariablesTemperature (naturally controlledLight enduringness (naturally controlledCarbon dioxide concentration (naturally controlledTime (controlled by using a stopwatchIndependent VariableConcentration of copper (II ) sulphate solutionDependent VariableRate of photosynthesisWILL AN INCREASE IN CONCENTRATION OF COPPER II (IONS ) DECREASE THE RATE OF PHOTOSYNTHESIS FROM alga 3Apparatus and MaterialsApparatus Quantity /Amount Electronic balance -0 .0005g )1100ml beaker 1Filter funnel 1L-shaped connecting tubes 1Tube-connector 1Drop of warp 130 cm ruler -0 .05cm )11M CuSO4 1 small nursin! g bottle (at to the lowest degree 250mlWet sea algae 20gSea water 400mlStopwatch -0 .
