1. Monday, December 12, 2011 PLANNER: LOGBOOK CHECK AND QUIZ ON BLOCK DAY CONCLUSION WRITING ASSIGNMENT ON FRIDAY

2. Make a new logbook entry – What is Cellular Respiration in Plants?-12/12 - Answer the Warm-up questions below: What two things do we (animals) get from our food? How do we (animals) get the energy from our food? What is the equation for this process?

3. So far, we have seen that plants take carbon dioxide and water from the environment to build carbohydrates. These carbohydrates are used to make the plant get larger. Fill in the MATTER diagram that shows how the CARBON (from CO 2 ) changes as it used by the plant for growth (starch or cellulose is okay) Environment Leaf/Stem GLUCOSE CO 2 Leaf/Stem STARCH or CELLULOSE

4. Read- What is Cellular Respiration in Plants? Glue in and answer questions in LogBook

5. 1. WHY DO PEOPLE AND PLANTS BOTH NEED GLUCOSE? 2. AFTER GLUCOSE IS MADE IN THE LEAF CELLS, WHERE IS IT TRANSPORTED? FOR THE SAME REASONS—TO DO THINGS THAT KEEP OUR BODIES WORKING TO ALL PARTS OF THE PLANT—ROOTS, STEMS, LEAVES, FLOWERS

6. 3. WHAT TWO THINGS DO PLANTS DO WITH GLUCOSE? 4. INTO WHAT TYPE OF ENERGY DO PLANTS CHANGE THE CHEMICAL ENERGY IN GLUCOSE? USE IT FOR GROWTH (STARCH/CELLULOSE) OR USE IT FOR ENERGY MOTION (KINETIC) AND THERMAL

7. 5. WHAT ARE EXAMPLES OF THINGS PLANTS DO THAT WOULD REQUIRE KINETIC ENERGY? (Plant movement- Coleus- gravitism and cool corn phototropism:http://plantsinmotion.bio.indiana.edu /plantmotion/movements/tropism/tropisms.html)http://plantsinmotion.bio.indiana.edu /plantmotion/movements/tropism/tropisms.html 6. OTHER THAN KINETIC ENERGY, WHAT KIND OF ENERGY IS PRODUCED WHEN PLANTS USE GLUCOSE? MOVING, GROWING, TRANSPORTING THERMAL

9. 7. IN ADDITION TO GLUCOSE, WHAT OTHER MOLECULE IS NEEDED TO PERFORM CELLULAR RESPIRATION? 8. COMPARE THE INPUTS AND OUTPUTS OF CELLULAR RESPIRATION AND PHOTOSYNTHESIS. OXYGEN—JUST LIKE C.R. IN ANIMALS OR BURNING A MARSHMALLOW CO2 + H2O GLUCOSE (CHEMICAL ENERGY) + O2 SUN GLUCOSE (CHEMICAL ENERGY) + O2 CO2 + H2O C.E & T.E.

10. 9. WHAT TWO MOLECULES ARE RELEASED BY PLANTS THAT ARE EVIDENCE OF CELLULAR RESPIRATION? MATTER: Glucose(C 6 H 12 O 6 ) + 6Oxygen(O 2 ) → 6Carbon Dioxide(CO 2 ) + 6Water (H 2 O )

13. Class Avg.12345678910Avg(g) Change in plant mass (g) (from seed to plant) -.31-.36-.39-.35-.41-.40-.31-.28-.34-.24 -.34 Plants in the DARK mass change (10 Class Average) - THIS MEASUREMENT WAS THE DIFFERENCE IN THE SEEDS AND THE PLANT THEY GREW INTO AFTER 4 WEEKS. - ALL CLASSES REPORTED A DECREASE IN MASS FORF THE PLANTS IN THE DARK

14. THE PLANTS DEFINITELY INCREASED IN HEIGHT— IN FACT, THEY WERE SIGNIFICANTLY TALLER THAN THE PLANTS IN THE LIGHT. EXPLAIN WHY THE PLANTS IN THE DARK WERE ABLE TO GROW EVEN THOUGH THEY COULDN’T DO PHOTOSYNTHESIS. BE SURE TO EXPLAIN WHY THE PLANTS HAD LESS MASS THAN THE SEEDS THEY STARTED AS—AND—WHERE THE MATTER (MOLECULES) WENT (WHERE IS THE MISSING 0.34 GRAMS?)

15. -Plants in the dark used stored energy (starch) from the beans. -They weighed 0.34 grams less at the end because the mass (carbon) was broken apart in Cellular Respiration to release energy to grow. This produced CO2 (missing matter) which went into the air.

17. What would you predict about the amount of starch in a plant that was sprouted/grown in the dark vs the light? -More starch than normal OR -Normal amount of starch OR -Less than normal amount of starch Why? Plant was unable to produce glucose through photosynthesis. It only performed cellular respiration which depleted stored energy (starch) without replacing it through photosynthesis.

18. NO LIGHT Leaf Leaf in LIGHT WHY WOULD THE LEAF IN THE DARK HAVE NO STARCH? THE SEED CONATINED STARCH—WHAT HAPPENED TO IT? WHAT PROCESS USED THE STARCH/GLUCOSE?

19. Make a new entry- Checkup Ideas Fix-Up-12/12 Get a sheet from the front counter and a form “A” or form “B” checkup

20. FOOD FOR PLANTS QUIZ REVIEW!

21. WHO HAS THE BEST IDEA ABOUT HOW PLANTS USE FOOD AND WHY?

25. LEAF CELL THAT ALLOWS CO 2 IN

26. VASELINE

27. LEAF CELL WITH CO 2 BLOCKED

28. Building glucose requires energy as an INPUT Glucose Carbon dioxide molecules

29. Breaking glucose releases energy as an OUTPUT Kinetic energy 60% will be lost right away as heat/thermal and 40% will be converted to a “useful” form of energy--ATP

30. LIGHT ENERGY CHEMICAL ENERGY Glucose Carbon dioxide PPP PPP ENERGY FOR CELLULAR WORK ATP ADP P+ Matter cycles as energy is transformed CO 2 Glucose Energy from Cellular Respiration ADP + P ATP

31. SHOW THE CHANGES IN MATTER AND ENERGY AS A PLANT MAKES FOOD- THEN USES IT FOR A ENERGY-REQUIRING PROCESS (MOVEMENT, ETC) SUN/LIGHT CO 2 H2OH2O GLUCOSE CHEMICAL O2O2 KINETIC THERMAL CO 2 H2OH2O

32. Get a set of matter and energy cards (1 set of each per table) These CAN be used to help you answer questions 1-4 on the back of your review

33. Glucose In cell Chemical Energy Environment Thermal ATP in Stem or Flower cell Chemical Energy Stem or Flower cell Kinetic Environment Thermal #4
