Give one reason for your answer. [2 marks] Cell Reason 01.2 Which cell is a prokaryotic cell? Give one reason for your answer. [2 marks] Cell Reason 01.3 A scientist observed a cell using an electron microscope. The size of the image was 25 mm. The magnification was  100 000 Calculate the real size of the cell. Use the equation: Give your answer in micrometres. [3 marks] Real size = micrometres 0 2 Plants absorb light to photosynthesise. 0 2 . 1 What is the correct word equation for photosynthesis? [1 mark] Tick one box. 0 2 . 2 Figure 2 shows some of the apparatus that can be used to measure the rate of photosynthesis. Figure 2 The rate of photosynthesis in the pondweed is affected by different colours of light. Describe a method you could use to investigate this. You should include: what you would measure variables you would control. [6 marks]
