b) Phycobilins
c) Chlorophyll
d) Xanthophylls
Which pathway is used by desert plants to survive in hot conditions?
a) C3 pathway
b) C4 pathway
c) CAM pathway
d) Krebs cycle
Section 2: Short-Answer Questions
What are the three main stages of the Calvin cycle?
Why is photorespiration considered wasteful for plants?
What is the difference between cyclic and non-cyclic photophosphorylation?
Name two products of the Krebs cycle.
How does glycolysis contribute to ATP production?
Discussion Topics
Now that you’ve answered the quiz questions, let’s discuss some interesting topics. Think about these questions and share your ideas:
Metabolism and Agriculture:
How do farmers use their knowledge of metabolic pathways to improve crop yield?
Can we modify photosynthesis to make plants grow faster?
Energy and Survival:
Why do some plants use C4 and CAM pathways instead of the C3 pathway?
How do metabolic processes help plants survive in extreme conditions (e.g., drought, cold)?
Sustainability and Climate Change:
How does plant metabolism affect global carbon dioxide (CO₂) levels?
Can understanding plant metabolism help in combating climate change?
Student Presentations
It’s time for you to present what you’ve learned! Choose one of these topics and prepare a short presentation (3-5 minutes) explaining it in your own words. Use real-life examples and keep it engaging!
Presentation Topics:
The Role of ATP in Metabolism – How does ATP store and release energy?
Comparing Photosynthesis and Cellular Respiration – How are these two processes connected?
Why C4 and CAM Plants Are Important – Explain how these plants survive in harsh environments.
The Krebs Cycle Explained – What happens during this important energy-producing process?
How Humans Benefit from Plant Metabolism – What role do metabolic pathways play in medicine, food production, or climate change?
Wrap-Up: Why This Matters
Metabolism is the key to life—without it, plants wouldn’t grow, and we wouldn’t have oxygen, food, or energy! Understanding these pathways helps scientists and farmers improve plant growth, develop sustainable agriculture, and even combat climate change.
Reflection: Your Turn to Think!
