  5. Thylakoid
  1. a yellow or orange pigment that serves as an accessory to chlorophyll in photosynthesis
  2. b The distance between crests of electromagnetic waves.
  3. c type of plant that minimizes photorespiration by fixing carbon twice, using a C4 pathway in addition to the Calvin-Benson Cycle.
  4. d one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules
  5. e A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy.

5 Multiple choice questions

  1. Store the organic acids made at night in vacuoles and use them for photosynthesis during the day when stomata are closed
  2. the synthesis of organic compounds from carbon dioxide, such as in photosynthesis
  3. process by which plants use the sun's energy to convert water and carbon dioxide into sugars
  4. The ground tissue of a leaf, sandwiched between the upper and lower epidermis and specialized for photosynthesis.
  5. An instrument that measures the proportions of light of different wavelengths absorbed and transmitted by a pigment solution.

5 True/False questions

  1. photophosphorylationA metabolic pathway that consumes oxygen, releases carbon dioxide, generates no ATP, and decreases photosynthetic output.


  2. primary electron acceptorin chloroplasts, an acceptor of electrons lost from chlorophyll a; found in the thylakoid membrane


  3. Chlorophyll bA photosynthetic pigment that participates directly in the light reactions, which convert solar energy to chemical energy.


  4. Rubiscoenzyme that converts inorganic carbon dioxide molecules into organic molecules during the final step of the calvin cycle


  5. photosystem IIOne of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P680 reaction-center chlorophyll.
