  7. Conditions for Photosynthesis W.S. p. 16 Design expt.

  8. Conditions for Photosynthesis W.S. p. 16 Carbon dioxide Design expt. Carbon dioxide starch V V V V Put 2 green leaves inside 2 colourless bags A and B respectively. Add a bag of soda lime in bag A. 4. After 4 hours, test the 2 leaves for starch. Carbon dioxide Yes No Carbon dioxide No Carbon dioxide

  9. W.S. p. 17 Burning & Respiration carbon Carbon dioxide water Carbon dioxide + water + energy oxygen Carbon dioxide water Energy respiration Carbon dioxide + water + energy

  10. W.S. p. 17 Oxygen Carbon dioxide water Energy Slow Controlled In the presence of fuel and oxygen all living cells

  11. W.S. p. 18 Breathing, Burning & Respiration Bronchus Trachea Blood vessels upwards inwards downwards outwards downwards upwards increases decreases decreases increases in out

  12. W.S. p. 18 Mechanical / physical ribs diaphragm Mechanical/physical chemical diaphragm ribs energy chemical Heat energy, sound energy, Kinetic energy breathing Respiratory system

  13. W.S. p. 19 Photosynthesis Carbon dioxide +sunlight+ chlorophyll water starch oxygen To kill the cells and make it soft To remove chlorophyll To wash away the alcohol To test for starch

  14. W.S. p. 19

  15. W.S. p. 19 Oxygen + Food Carbon dioxide + water Carbon dioxide + water Starch + oxygen Oxygen Carbon dioxide Carbon dioxide Oxygen Chemical energy  heat energy, sound energy Light energy  Chemical energy All living cells Chlorophyll All the time At day time
