A nematode that has parasitized a plant root has breached the cutin layer of the epidermis.

Question

Answer the following statement true (T) or false (F)

Answer 1

False

Clarify Question
• What is the key concept addressed by the question?
        o This question is asking about the nature of a nematode infection in terms of plant tissue.
• What type of thinking is required?
        o You are being asked to take what you already know and apply-it to effects of a parasitic infection to a plant.
• What key words does the question contain and what do they mean?
        o Nematode, which refers to a large group of animals that include roundworms.
        o Cutin, which is a waxy compound that is found in plant tissues.
        o Epidermis, which is the outer tissue of a plant.

Gather Content
• What do you already know about how nematodes infect plants? How does it relate to the question?
        o Suberin covers the epidermis of the root.
        o Nematode parasites attack the roots of a plant.

Consider Possibilities
• What other information is related to the question? Which information is most useful?
        o Cutin is found in plant tissues that occur above ground level.

Choose Answer
• Given what you now know, what information and/or problem solving approach is most likely to produce the correct answer?
        o Since nematodes attack plant roots, and cutin is not associated with plant root structure, cutin would not be breached with a nematode attack.

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 assess the effects of a nematode invasion on plant tissue.  Answering this question correctly depended on your ability to use your knowledge of plant tissues in a new situation.  If you got the correct answer, great job! If you got an incorrect answer, where did the process break down? Did you remember that cutin is associated with structures that grow above ground level, or that nematodes attack the roots of plants? Did you have trouble extending your knowledge of plant tissues to determine the correct answer?
