  1. The Secret of Life

  2. All living things need food. Some animals eat plants, some eat other animals – and some eat both.

  3. Food contains the chemical energy the body uses to do things – like run, think and grow.

  4. Trees and other plants don’t eat food. Where do they get the chemical energy they need to live and grow?

  5. } Photosynthesis the process plants use to make food

  6. Plants use water, carbon dioxide and sunlight AIR SUNLIGHT WATER to make a sugar called glucose, which contains the chemical energy they need.

  7. • The waterused for photosynthesis is in the soil. Water gets to the leaves via the roots.

  8. • Plants use carbon dioxidefrom the air to make glucose.

  9. Photosynthesis occurs in the plant cellsin the leaves.  Plant Cell

  10. • Sunlight energy hits the chlorophyll found in the cells which splits the water molecules into hydrogen and oxygen.

  11. In the process, the carbon dioxidemolecules are split into carbon and oxygen atoms. •

  12. The atoms from these raw materials recombine to form a glucose molecule: 6 Carbon Dioxide 6 Water 1 glucose 6 oxygen The carbon atoms form a chain with hydrogen and oxygen atoms attached to it.

  13. The products of photosynthesis are glucose and oxygen. Oxygen Bubbles  Oxygen molecules not needed to build glucose are released into the air. This adds oxygen to the air we breathe.

  14. The photosynthesis equation is: +6CO2+6H2O C6H12O6+6O2 + carbon +waterglucose+oxygen dioxide Sunlight

  15. In photosynthesis light energy is transformed into chemical energy in the form of glucose. Light Energy Photosynthesis Chemical Energy The glucose molecules formed during photosynthesis store the chemical energy that plants need to grow, bloom, and produce fruit.

  16. } Respiration the process plants use to release energy stored in glucose molecules

  17. Photosynthesis +6CO2+6H2O C6H12O6+6O2 + carbon +waterglucose+oxygen dioxide Sunlight NOTICE ANYTHING? Respiration E C6H12O6+6O2 6CO2+6H2O+ glucose+oxygen carbon +water + dioxide Energy

  18. • • • • When oxygen combines with glucose it splits apart and energy is released water carbon dioxide – and what’s left is: carbon dioxide and water.

  19. Plants respire during the day and at night.

  20. • The energy released when glucose breaks down into water and carbon dioxide is the energy plants use to grow and repair themselves.
