If you need help, please look at… Page 7L and 12R in your notebook Page 93 and 94 in your textbook Chloroplasts Mitochondria 1. Only in the plant cell 1. In BOTH plant and animal cells 2. MAKES sugar (stored energy) 2. RELEASES usable energy from sugar 3. Needs to absorb sunlight, so must have chlorophyll 3. Does not need sunlight, so does not have chlorophyll 13L

Which organelle does cellular respiration??? Do Now: Chloroplast vs. Mitochondria OQC 9/1/11 9/1/11 Standard 1d: Students know that mitochondria release energy for the work that cells do. How are chloroplasts and mitochondria different???? If you need help, please look at… Page 7L and 12R in your notebook Page 93 and 94 in your textbook Objective: Students will be able to compare and contrast photosynthesis to cell respiration by interviewing a chloroplast or a mitochondria. Unit 1: Cells—Vocabulary (continued) 11. Cellular respiration= the process of releasing energy from glucose Chloroplasts Mitochondria Which organelle does cellular respiration??? MITOCHONDRIA!!! 13L 13R

Notes: Cellular Respiration 9/1/11 OQC “Beach Ball” Review of Cellular Respiration Why do ALL cells have mitochondria? 2. What is the equation for cellular respiration? 3. How is cellular respiration similar to fire? (Hint: What do they both need and produce?) 4. Which types of cells in your body would need to have MANY mitochondria? (Hint: Which cells need A LOT of energy?) 5. What do cellular respiration and photosynthesis have in common? 9/1/11 Notes: Cellular Respiration A. What is sugar? STORED energy All cells have mitochondria because they all need to release energy from sugar. B. Who needs sugar? ALLLLLL cells!!!!!!!!! C. How does sugar get to the cells? 2. Sugar + oxygen  carbon dioxide + water + ENERGY (raw materials) (products) Heterotrophs must EAT other organisms Autotrophs must MAKE their own sugar (This is called PHOTOSYNTHESIS!!!!) D. Why do all cells need sugar? Sugar has LOTS of energy stored inside! E. How does the stored energy in sugar get released? 3. Both cellular respiration and a fire need oxygen. Both “BURN” a fuel to release energy. Mitochondria breaks down the sugar and RELEASES its stored energy for the cell to use! 4. Muscle cells!!! Especially when you are running the mile!!!! WHAT IS THIS CALLED???? CELLULAR RESPIRATION!!!! G. What does the mitochondria NEED to do cellular respiration? Oxygen and sugar!!! 5. Both are part of the cell energy cycle. Also, both keep the levels of carbon dioxide and oxygen in the atmosphere balanced. H. What are the products of cell respiration? Carbon dioxide, water, and USABLE ENERGY Carbon dioxide Oxygen 14L 14R

Use page 126 in your textbook to help you fill it out!!! Photosynthesis Cellular Respiration 1.What is the goal? 2.Which organelle does it? 3.Which cells do it? 4.What are the raw materials? 5.What are the products? 6.Draw this process 7.What is similar in real life? Directions: Please TAPE in this half sheet on TOP of your Review questions on page 14L!!! Use page 126 in your textbook to help you fill it out!!! You will have some questions on the QUIZ about this, sooooo….GOOD LUCK!!!

Photosynthesis Cellular Respiration 1.What is the goal? 2.Which organelle does it? (chloroplast or mitochondria?) 3.Which cells do it? (plant or animal?) 4.What are the raw materials? (The ingredients that are needed.) 5.What are the products? (The stuff that gets made.) 6.Draw this process (Include the sun, the organelle, raw materials, and products, use arrows) 7.What is similar in real life?

To RELEASE energy from sugar Chloroplast Mitochondria Plant cells Photosynthesis Cellular Respiration What is the goal? To MAKE sugar To RELEASE energy from sugar Which organelle does it? Chloroplast Mitochondria Which cells do it? Plant cells ALL cells What are the raw materials? Carbon dioxide + water  Sugar + Oxygen What are the products? Carbon dioxide + water + ENERGY Draw this process: What is similar in real life? Solar panels make electricity for a house. Fire uses oxygen to burn fuel and release energy.
