Flashcards (5) Click to reveal answers
Card #1
Front (Question/Term)
A crop shows "stunted stems" and "abnormally small leaves." If a Zinc deficiency is to blame, what is happening at the molecular level?
Back (Answer/Definition) ANSWER
The plant is unable to produce the amino acid tryptophan, the precursor to growth hormones (auxins).
Card #2
Front (Question/Term)
A farmer notices "mottled, chlorotic yellowing" on his leaves. If this is a Manganese deficiency, which process is directly impaired?
Back (Answer/Definition) ANSWER
Oxidative metabolism and photosynthetic oxygen production.
Card #3
Front (Question/Term)
Why is "Molybdenum" considered an essential micronutrient for plants that are specifically grown using "Nitrate" fertilizers?
Back (Answer/Definition) ANSWER
It is a critical component of the enzyme nitrate reductase, which allows the plant to use nitrate as a nitrogen source.
Card #4
Front (Question/Term)
If a plant is deficient in "Boron," what physical malformations would you expect to see based on your study material?
Back (Answer/Definition) ANSWER
Abnormally dark foliage, growth abnormalities, and stunted root tip elongation.
Card #5
Front (Question/Term)
A gardener sees "dark green and twisted" young leaves with "dead spots" (necrotic areas). Why does a deficiency in Copper lead to these specific symptoms?
Back (Answer/Definition) ANSWER
Copper is a component of enzymes and cytochromes; its absence lowers the rate of protein synthesis.
