Why does potassium hydrogencarbonate encourage photosynthesis




















The volume of oxygen produced could be measured by collecting the gas produced in a gas syringe. The changes in the oxygen or carbon dioxide concentration in the water could be measured using datalogging equipment. You could investigate the effect of different wavelengths of light on photosynthesis.

Use coloured acetate filters to investigate the effects of the blue, green and red parts of the spectrum on photosynthesis. The effect of the presence or absence of chlorophyll on photosynthesis can be investigated using a variegated plant.

Variegated plants have regions of their leaves with and without chlorophyll. Only those areas of the leaf with chlorophyll photosynthesise. They will test positive for starch, which is built up from the glucose produced.

Care must be taken when using boiling ethanol. Make sure that no Bunsen burners are turned on as the ethanol is highly flammable. All the other conditions in the greenhouses were kept the same. The fruit from the plants was collected and weighed when it was ripe. Why was it important in this experiment that all the conditions in the greenhouse, except for carbon dioxide concentration and the light intensity, were kept the same?

What was the yield of fruit up to 15 May when the plants were grown under normal conditions? What was the increase in the yield up to 15 May when the plants grown under normal conditions were given extra light and extra carbon dioxide? What is the importance of experiment 1 in this investigation? To 15 June did extra carbon dioxide or increase in light intensity have the greater effect upon the yield of tomatoes?

Why is the increase in yield greater between 15 June and 15 July than between 15 May and 15 June? Write down the equation either in words or in symbols for the process of hotosynthesis.
