GCSE Biology Photosynthesis

  1. 1. Starter What do I need to live a healthy life?
  2. 2. Learning Outcomes <ul><li>Photosynthesis </li></ul><ul><li>ALL Write out the equation for photosynthesis </li></ul><ul><li>MOST Describe how the leaf is designed for photosynthesis </li></ul><ul><li>SOME Explain why photosynthesis is needed </li></ul>
  3. 4. <ul><li>Fill in the word gaps on page 1 </li></ul>Summarise the animation
  4. 5. Photosynthesis Chloroplasts Filled with a green pigment called Chlorophyll Carbon dioxide + Water Glucose + Oxygen Sunlight Chlorophyll Study the diagram on page 2 and answer the questions
  5. 6. Leaf Structure
  6. 7. Activity - Bioviewers <ul><li>Using the bioviewer, choose 3 different </li></ul><ul><li>types of plant cell to draw. </li></ul><ul><li>For each cell type </li></ul><ul><ul><li>Describe the cells function (job) </li></ul></ul><ul><ul><li>Describe any adaptations it has to perform this job </li></ul></ul>Complete the questions on page 3 & 4 using the diagram and the knowledge you have gained. Use the text book to help if needed.
  7. 8. CARD SORT ACTIVITY Sort the cards to match the diagram. Once you have sorted the cards ask the teacher to check they are correct before writing on your worksheet.
  8. 9. Rate of photosynthesis How would we measure how fast photosynthesis happens? sunlight Plants make oxygen when they photosynthesis… An experiment was carried out to see how different light intensities effected the rate of photosynthesis On a sunny day there is more light! … we can measure how much oxygen is made in one minute The more oxygen is made the faster photosynthesis MUST be happening! 1 2 3 4 5 6 Number of bubbles in 1 minute Light level (in lux)
  9. 10. Rate of photosynthesis
  10. 11. Rate of photosynthesis sunlight Answer the questions and plot the graph on pages 4 – 7 in your work book 30 60 87 108 111 112 1 2 3 4 5 6 Number of bubbles in 1 minute Light level (in lux)
  11. 12. Learning Outcomes <ul><li>Photosynthesis </li></ul><ul><li>ALL Write out the equation for photosynthesis </li></ul><ul><li>MOST Describe how the leaf is designed for photosynthesis </li></ul><ul><li>SOME Explain why photosynthesis is needed </li></ul>
  12. 13. Plenary <ul><li>Answer the practice exam question </li></ul>
