If the soil around a plant is treated with a fungicide, the plant may experience a decline in DNA synthesis.
Answer the following statement true (T) or false (F)
True
Clarify Question
What is the key concept addressed by the question?
• The key concept is the role of fungi in the life of plants.
What type of thinking is required?
o You are being asked to take what you already know and apply it to a new situation in which fungi are removed from their plant symbionts.
What key words does the question contain and what do they mean?
• Fungicide, which is a chemical that kills fungi.
• DNA, which is the genetic material of living things.
• Synthesis, which means to produce.
Gather Content
What do you already know about the role that fungi play in plant cell function? How does it relate to the question?
• Mycorrhizzal fungi are associated with the roots of certain plants.
• Myco refers to fungi, while rhizzal pertains to roots.
• These fungi aid the absorption of water and minerals from the soil.
• Phosphorus absorption from the soil is especially enhanced.
• Phosphorus is an important building block of DNA.
Consider Possibilities
What other information is related to the question? Which information is most useful?
• Since DNA synthesis is dependent on available building blocks, mycorrhizal fungi would aid this process by making phosphorus available.
Choose Answer
Given what you now know, what information and/or problem solving approach is most likely to produce the correct answer?
• To answer this question, you must connect the concept of associating with mycorrhizal fungi, the minerals they make available, and the role those minerals play in DNA synthesis.
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?
• This question asked you to identify the contributions of mycorrhizal fungi to plant biology. Answering this question correctly depended on your ability to use the idea that these fungi contribute minerals to plants 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 these fungi make phosphorus available, or that phosphorus is a building block of DNA? Did you have trouble extending this benefit of mycorrhizal assocation to determine the correct answer?
