  2. b The green tissue in the interior of the leaf
  3. c A light-absorbing pigment in the chloroplasts that plays a central role in the chloroplasts
  4. d Organisms that make their own food and thus sustain themselves without consuming organic molecules derived from any other organisms

5 Multiple choice questions

  1. Transform light energy to chemical engergy stored in the bonds of sugar they make from carbon dioxide and water
  2. Alternate modes of carbon fixation have evolved that save water without shutting down photosynthesis. Preced the Calvin cycle by first fixing CO2 into a four-carbon compound. Keeps its stromata mostly closed
  3. A fixed quantity of light energy
  4. Interconnected membranous sacs suspended in the stroma

5 True/False questions

  1. Regeneration of RuBPA series of chemical reactions uses energy from ATP to rearrage the atoms in the five G3P molecules (15 carbons total), forming three RuBP molecules (15 carbons). These can start another turn of the cycle

          

  2. Carbon fixationRubisco combines CO2 with a five-carbon sugar called ribulose bisphosphate (RuBP). The unstable product splits into two molecules of the three-carbon organic acid, 3-phosphoglyceric acid (3-PGA). For three CO3 entering, six 3-PGA result

          

  3. WavelengthAlternate modes of carbon fixation have evolved that save water without shutting down photosynthesis. Preced the Calvin cycle by first fixing CO2 into a four-carbon compound. Keeps its stromata mostly closed

          

  4. PhotoautotrophsOrganisms that produce organic molecules from inorganic molecules using the energy of light

          

  5. GranaStacks of thylakoids
