A mutant form of an Arabidopsis thaliana plant has defective chlorophyll production, such that the abundance of chlorophyll molecules in chloroplasts is 5% the normal level, and the chlorophyll molecules are on average too far apart for resonance energy transfer to occur. What will be the effect on the overall efficiency of photosynthesis in the plant? Rationalize your answer

Using good organization skills, check over your map of the steps in photosynthesis. Your flowchart should include these concepts and details: • location in the organelle the reactions occur, • the type of biochemical reactions or cellular transport, • the substrates and products for the overall process, • vocabulary and terminology that allow you to demonstrate your understanding. Ask yourself these big questions as a way to monitor and improve your work: • Is the information I have presented a complete representation of my learning? • Is the information I have presented correct? • Have I fulfilled the requirements of the task? • Are the steps I describe organized in the correct order?
