  4. The World of Cells 1 Energy and the Cell • Cells, except bacteria, have organelles called mitochondria (mi tuh KAHN dree uh). • An important process called cellular respiration takes place inside a mitochondrion.

  5. The World of Cells 1 Energy and the Cell • Cellular respiration is a series of chemical reactions in which energy stored in food is converted to a form of energy that the cell can use.

  6. The World of Cells 1 Energy and the Cell • This energy is released as food and oxygen combine. • Waste products of this process are carbon dioxide and water.

  7. The World of Cells 1 Nature's Solar Energy Factories • Animals obtain food from their surroundings. • Plants, algae, and many types of bacteria make food through a process called photosynthesis(foh toh SIHN thuh sus).

  8. The World of Cells 1 Nature's Solar Energy Factories • Most photosynthesis in plants occurs in leaf cells. • Inside these cells are green organelles called chloroplasts(KLOR uh plats).

  9. The World of Cells 1 Nature's Solar Energy Factories • During plant photosynthesis chloroplasts capture light energy and combine carbon dioxide from the air with water to make food. • As the plant needs energy, its mitochondria release the food's energy.

  10. Read the article “Photosynthesis and cellular respiration” http://www.buzzle.com/articles/photosynthesis-and-cellular-respiration.html and read textbook p. 480-481 • Students will categorize information about both processes using cutout info and blank title papers • After they are checked for correctness, they will record info on notes

  11. Read the article “Photosynthesis and cellular respiration” http://www.buzzle.com/articles/photosynthesis-and-cellular-respiration.html and read textbook p. 480-481 • Compare

  12. Section Check 1 Question 3 Where is food energy changed into a form of energy that a cell can use? A. chloroplast B. nucleus C. mitochondrion D. vacuole

  13. Section Check Section Check 1 Answer The correct answer is C. Mitochondria are bean-shaped organelles.
