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. 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. 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). 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). 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. Read the article “Photosynthesis and cellular respiration” http://www.buzzle.com/articles/photosynthesis-andcellular-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 Read the article “Photosynthesis and cellular respiration” http://www.buzzle.com/articles/photosynthesis-andcellular-respiration.html and read textbook p. 480-481 • Compare Photosynthesis only Cellular respiration only Photosynthesis only Cellular respiration 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 Section Check 1 Answer The correct answer is C. Mitochondria are bean-shaped organelles.
