2. Copy these questions 1WHY IS ENERGY NEEDED BY EVERY ORGANISM? 2WHAT IS THE ULTIMATE SOURCE OF ENERGY FOR EVERY ORGANISM? 3WHAT IS THE HIGH ENERGY MOLECULE STORED IN THE CELLS? 4 HOW MANY PHOSPHATE GROUPS ARE ATTACHED TO THE ATP MOLECULE? ADP? 5WHY DOES ATP HAVE MORE ENERGY THAN ADP? 6WHAT HAPPENS TO RELEASE ENERGY FROM THE ATP MOLECULE? 7WHAT IS THE EQUATION THAT REPRESENTS PHOTOSYNTHESIS? 8WHAT COMPOUNDS ARE NEEDED FOR PHOTOSYNTHESIS? 9WHAT ARE THE TWO PHASES OF PHOTOSYNTHESIS? 10WHAT CARBOHYDRATE PLANTS PRODUCE DURING PHOTOSYNTHESIS? 11WHAT ENERGY COMPOUND IS PRODUCED DURING THE LIGHT PHASE? 12WHERE IN THE LEAF IS CHLOROPHYLL STORED? 13 WHAT IS THE FUNCTION OF THE CHLOROPHYLL IN THE PROCESS OF PHOTOSYNTHESIS? 14WHAT CAUSES LEAVES TO BE GREEN?

3. ENERGY 1. ENERGY IS NEEDED BY EVERY ORGANISM FOR ALL NORMAL LIFE PROCESS. 2. THE SUN IS THE ULTIMATE SOURCE OF ENERGY FOR ALL LIFE! 3. ADENOSINE TRIPHOSPHATE (ATP)

4. ATP IS THE HIGH ENERGY COMPOUND 4. ATP HAS THREE PHOSPHATE GROUPS ATTACHED TO THE ADENOSINE MOLECULE, ADP HAS ONLY TWO PHOSPHATE GROUPS ATTACHED. 5. IT TAKES MORE ENERGY TO ATTACH MORE PHOSPHATES, THEREFORE ATP IS HIGHER IN ENERGY.

5. ATP TO ADP 6. BREAKING THE CHEMICAL BOND BETWEEN ONE PHOSPHATE GROUP AND THE ADENOSINE MOLECULE IN ATP RELEASES ENERGY AND LEAVES AN ADP MOLECULE. (T STANDS FOR TRI AND D STANDS FOR DI)

6. PHOTOSYNTHESIS 7. We can write the overall reaction of this process as: 6H 2 O + 6CO 2 ----------> C 6 H 12 O 6 + 6O 2

7. 8. COMPOUNDS NEEDED CARBON DIOXIDE ENTERS THE PLANT THROUGH THE STOMA WATER ENTERS THE PLANT THROUGH THE ROOTS CHLOROPHYLL IS STORED IN THE CHLOROPLAST IN THE PLANT CELLS

8. 9. LIGHT AND DARK REACTIONS 10. PLANTS PRODUCE GLUCOSE 11.

9. 12. CHLOROPHYLL IS STORED IN THE LEAF 13. 14. CHLOROPHYLL
