Photosynthesis Revision 10 İ

Which of the following equations represents photosynthesis? 6H2O + 6O2 → C6H12O6 + 6CO2 6CO2 + 6H2O → C6H12O6 + 6O2 C6H12O6 + 6O2 → 6CO2 + 6H2O 6CO2 + 6O2 → C6H12O6 + 6H2O C6H12O6 + 6CO2 → 6O2 + 6H2O Match the words with definitions. ETC Connects the two photosystems in the light reactions ATP molecule that is produced in light dependent reactions and power the Calvin cycle H2O Provides electrons for the light dependent reactions CO2 Provides the carbon atoms that are incorporated into sugar molecules in the Calvin cycle NADPH Transports electrons from the light reactions to the Calvin cycle G3P Precursor of organic compounds RuBP Starts Calvin cycle with the help of rubisco enzyme Fill in the missing parts of the sentences. Light independent reactions are shown as cycles because RuBPsneeds to be formed again and again. There are 3 different phases in Calvin cycle.Firstly, Rubiscoenzyme helps to take carbon dioxide in the atmosphere and attaches it to ribulose bisphosphate. This is called CO2 fixation.Secondly, there are many steps until we get G3Ps. The molecules that come from light dependent reactions power and give electrons to these stages. When molecules take electrons, they are reduced. That is why we call these stages as reduction phases. At the end of these stages G3Ps are formed and some of them are used to produce organic compounds. So, we understand why we call plants as autotrophs!Lastly, the rest of G3Ps are converted in to RuBP again and it is called regeneration phase. Use (you can copy and paste) the words to show missing parts of the figure.

Finally she made a chart and draw a graph to show the data.Next day when she came back to laboratory, she noticed that somebody erased the last result of the chart. She looked at the graph and filled in the missing part. What did she write? 119 Plants need minerals to maintain photosynthesis and growth. The plant on the right is healthy. Which mineral limits the growth of plant on the left? N P K Match the graphs with the factors. The effect of temperature The effect of water The effect of CO2 The effect of wavelenght
