A parasitic plant without chlorophyll is likely to lack leaves.
Answer the following statement true (T) or false (F)
True
Clarify Question
• What is the key concept addressed by the question?
o This question is asking about the nature of a parasitic plant.
• What type of thinking is required?
o You are being asked to take what you already know and apply it to how parasitic plants survive.
• What key words does the question contain and what do they mean?
o Parasitic, which involves one species that feeds off another.
o Chlorophyll, which is the chief light-absorbing pigment in photosynthesis.
o Leaves, which are structures in which photosynthesis occurs.
Gather Content
• What do you already know about parasitic plants? How does it relate to the question?
o Chlorophyll absorbs light energy, which drives the process of photosynthesis.
o Leaves are the primary site of photosynthesis.
o Parasitic plants obtain their energy from other organisms.
Consider Possibilities
• What other information is related to the question? Which information is most useful?
o Since they lack chlorophyll, leaves would not be useful to the parasitic plant.
Choose Answer
• Given what you now know, what information and/or problem solving approach is most likely to produce the correct answer?
o To answer this question, the lack of chlorophyll must be correlated with a lack of photosynthesis. Since the plant is not photosynthetic, it would not need leaves.
Reflect on Process
• Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
• Apply level:
o This question asked you to understand the nature of parasitic plants. Answering this question correctly depended on your ability to connectthe concept of parasitic plants with the lack of need for leaves and chlorophyll. If you got the correct answer, great job! If you got an incorrect answer, where did the process break down? Did you remember that parasitic plants are not photosynthetic, or that the main function of leaves is photosynthesis? Did you have trouble extending the concept of parasitic plants to determine the correct answer?
