Unit Objectives:
Photosynthesis & Respiration


KNOWLEDGE of SUBJECT MATTER: 

Students should have knowledge of each of the following and be able to apply them in simple situations:

  1. explain the leaf structures and mechanism that regulate the exchange of gases and thus influence the plant's rate of photosynthesis
  2. recall the wavelengths of visible spectrum and the action and absorption spectra of photosynthesis
  3. understand that photosynthesis involves the conversion of light energy into chemical bond energy in the form of ATP

  4. describe the role of light and chlorophyll pigment in the two stages of photosynthesis

  5. recall the chemical equations for photosynthesis and respiration
  6. contrast photosynthesis with aerobic respiration and know the pathways taken by carbon atoms during these processes

  7. recall the site of respiration in eukaryotic cells
  8. understand and define the processes involved in cellular respiration

  9. explain the differences between aerobic and anaerobic respiration including the difference in ATP yield

  10. describe the role of enzymes in respiration

 


 


SIMPLE SCIENTIFIC PROCESSES:

Students should be able to:

  1. interpret experimental data relating to the role of enzymes

  2. use data to explain the effects of environmental differences on the rates of photosynthesis and respiration

  3. conduct experiments to acertain the role of enzymes
  4. investigate the relationship between transpiration rates and rates of photosynthesis
  5. perform calculations using data relating to photosynthesis and respiration

COMPLEX REASONING PROCESSES:

Students should be able to:

  1. evaluate experimental evidence relating to factors affecting both respiration and photosynthesis

  2. compare and contrast the processes of photosynthesis and respiration
