Answer 1

B.  auxin

Clarify Question
· What is the key concept addressed by the question?
        o The question is asking about the effect of seed removal from a fruit.
· What type of thinking is required?
        o You are being asked to take what you already know and apply it to the importance of seeds to fruit.
· What key words does the question contain and what do they mean?
        o Seeds, which are plant embryos.
        o Fruit, which is a seed-bearing structure produced by a plant.
        o Hormones, which are chemicals that can regulate processes in tissues.

Gather Content
· What do you already know about the relationship between seeds and fruit? How does it relate to the question?
        o A strawberry lacking seeds will not develop.
        o If treated with a synthetic auxin, the fruit will grow.

Consider Possibilities
· What other information is related to the question? Which information is most useful?
        o Ethylene is involved with ripening.
        o Gibberellins influence seed germination.
        o Strigolactones and oligosaccharides do not appear to have a role in fruit formation.

Choose Answer
· Given what you now know, what information and/or problem solving approach is most likely to produce the correct answer?
        o Auxin is involved with the formation of fruit.

· Apply level:
        o This question asked you to understand the importance of seeds to fruit. Answering this question correctly depended on your ability to use the characteristics of seeds 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 seeds contain hormones that influence fruit, or that auxin is a hormone that stimulates fruit formation? Did you have trouble extending the characteristics of seeds to determine the correct answer?
