Revising E Michaelmas Biology for 2016 trials

If you are revising for E Michaelmas trials next week, I suggest you go through this checklist and make sure you understand each point fully….. This list could be the basis for making some revision notes.

  • Understand the differences between atoms and molecules
  • What is a polymer?  Give some biological examples of polymers and describe their structure.
  • What are the chemical tests for glucose and starch?
  • How do enzymes work as catalysts?
  • Draw a graph to show how temperature effects the rate of an enzyme-catalysed reaction.  Annotate the graph to explain why this pattern is observed.
  • Now do the same but for the effect of pH on enzyme reactions…..
  • Write down the word and balanced chemical equations for photosynthesis.
  • Why is photosynthesis such an important process in the plant (and in the ecosystem)?
  • Draw an annotated diagram to show the structure of a leaf and how it is adapted for photosynthesis.
  • How do you test a leaf for starch?  How do you measure rates of photosynthesis using an aquatic plant? What variables could you alter in this set up?
  • Explain differences in function between xylem and phloem.
  • How is water absorbed in root hair cells?  Explain osmosis (good luck!)
  • What are the differences between diffusion and active transport?  Give two biological examples of each.
  • What is transpiration?  How can you measure it?
  • What factors affect rates of transpiration in a plant?
  • What is the difference between a pesticide and a fertiliser?
  • What are the advantages and disadvantages of chemical pesticides and biological control of pests?
