5 Matching questions

  1. Chlorophyll
  2. Photosystem
  3. Chloroplast
  4. Thylakoid
  5. Heterotroph
  1. a an organism that obtains organic food molecules by eating other organisms or their byproducts and that cannot synthesize organic compounds from inorganic materials
  2. b a membrane system found within chloroplasts that contains the components for photosynthesis
  3. c in the thylakoid membranes of chloroplasts, a cluster of chlorophyll and other pigment molecules that harvest light energy for the light reactions of photosynthesis
  4. d an organelle found in plant and algae cells where photosynthesis occurs
  5. e a green pigment that is present in most plant cells, that gives plants their characteristic green color, and that reacts with sunlight, carbon dioxide, and water to form carbohydrates

5 Multiple choice questions

  1. the initial reactions in photosynthesis, which are triggered by the absorbtion of light by photosystems I and II and include the passage of electrons along the electron transport chains, the production of NADPH and oxygen gas, and the synthesis of ATP through chemiosmosis
  2. an organism that produces its own nutrients from inorganic substances or from the environment instead of consuming other organisms
  3. a stack of thylakoids in a chloroplast
  4. in chloroplasts and mitochondria, a process in which the movement of protons down their concentration gradient across a membrane is coupled to the synthesis of ATP
  5. a class of pigments that are present in the thylakoid membrane of plants and that aid in photosynthesis

5 True/False questions

  1. Electron Transport Chaina series of molecules, found in the inner membranes of mitochondria and chloroplasts, through which electrons pass in a process that causes protons to build up on one side of the membrane

          

  2. Photosynthesisthe process by which plants, algae, and some bacteria use sunlight, carbon dioxide and water to to produce carbohydrates and oxygen

          

  3. Stomaone of many openings in a leaf or a stem of a plant that enable gas exchange to occur

          

  4. Calvin Cyclea green pigment that is present in most plant cells, that gives plants their characteristic green color, and that reacts with sunlight, carbon dioxide, and water to form carbohydrates

          

  5. C4 pathwaya water-conserving, carbon-fixing process; ____ plants take in carbon at night and fix it into various organic compounds and release it during the day
