Explain how the ATP and NADPH produced by the photosynthetic electron transport chain are used in the PCR cycle.

Resource: Appendix A

Create an 8- to 12-slide Microsoft® PowerPoint® presentation addressing the following points:

  • Provide a picture of a cross section of a leaf and label the following parts:  epidermis, guard cells, stomata, spongy mesophyll, palisade parenchyma, phloem, and xylem.
  • Describe the leaf anatomy by discussing the functions of the above structures (from question #1). Explain how that anatomy is ideally suited for photosynthesis.
  • Provide a picture of a cross section of a root and label the following parts:  root cap, root apical meristem, zone of elongation, zone of maturation, root hairs, cortex, vascular tissue, ground tissue, endodermis, and the Casparian strip.
  • Describe the root anatomy (describe the functions of the structures in question #3) and how that anatomy is ideally suited for growth and absorption of water and minerals from the soil.
  • Copy and paste the table from Appendix A into your slideshow. Complete the table with the nutrient functions and signs of deficiency.

Format references consistent with APA guidelines.

 

 

PART TWO

Resources: This week’s readings

Write a 50- to 75-word response for each bulleted area:

  • Explain how CO2 enters leaves. What environmental factors control stomatal movement? How are these factors related to physical and chemical properties that control the opening and closing of stomata?
  • What are primary stages in the photosynthetic carbon reduction (PCR) cycle? Explain the role of each stage. Draw a diagram of the stages by utilizing drawing tools in Microsoft® Word to aid your explanation.
  • Explain how the ATP and NADPH produced by the photosynthetic electron transport chain are used in the PCR cycle.
  • What roles do light and Rubisco play in regulating the PCR cycle? Explain your answer.
  • Explain how cells release energy through glycolysis, respiration, and fermentation. Identify pathways in each stage. Describe each stage’s role in releasing energy.
  • What is the role of enzymes in degrading starch and sugar? Explain your answer.
  • Discuss some similarities and differences between respiration and fermentation.
  • Aerobic organisms are usually larger than anaerobic organisms. Suggest how this might be related to respiration
