Pea plants are self-pollinators. What can you further deduce about peas? (Check all that apply.)A) Peas will be more resistant to garden pests than other plants.B) Peas are less likely to invade highly variable natural environments than other plants.C) A gardener planning to collect heirloom seeds can plant different varieties of peas near each other.D) Peas will be more resistant to new plant diseases.E) To perform his pea cross-pollination experiments, Gregor Mendel must have first removed the stamens from flowers to prevent self-pollination.

Question

What will be an ideal response?

Answer 1

B, C, E

Clarify Question
• What is the key concept addressed by the question?
        The question is asking about the consequences of self-pollination.
• What type of thinking is required?
        You are being asked to take what you already know and apply it to the effects of self-pollination to a plant and the plants in the surrounding area.

Gather Content
• What do you already know about pollination? What other information is related to the question?
        o Both pistils and stamens are found in the same flower on a self-pollinated plant.
        o Self-pollinated plants have lower genetic variability than cross-pollinated plants.
        o Self-pollination is favored in environments that have greater stability.

Choose Answer
• Given what you now know, what information is most likely to produce the correct answer?
        o Self-pollinated plants are not necessarily more resistant to garden pests or diseases.
        o If self-pollinating plants are grown next to each other, they maintain their own identities and traits, so different varieties could be easily differentiated.
        o To turn a self-pollinator into a cross-pollinator, the stamens must be removed.

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?
       o Answering this question correctly depended on your ability to use the characteristics of self-pollinating plants in a new situation. If you got an incorrect answer, did you remember that self-pollination removes the necessity for dispersion or that self-pollinated plants maintain their own unique identities? Did you have trouble extending the characteristics of self-pollinated plants to determine the correct answer?
