Question 1
Which plant enzyme directly fixes atmospheric carbon dioxide during the Calvin cycle of C3 crops such as wheat and barley?
Correct Answer:
Ribulose-1,5-bisphosphate carboxylase-oxygenase (RuBisCO)
Question 2
During periods of high daytime temperatures and drought stress, why do C3 crops experience a significant decline in photosynthetic efficiency compared to C4 crops?
Correct Answer:
RuBisCO oxygenase activity increases relative to carboxylase activity, leading to photorespiration
Question 3
A grower needs to apply 92 kg of elemental nitrogen (N) per hectare to a canola crop prior to stem elongation. If using Urea (46% N), how many kilograms of Urea fertilizer must be applied per hectare?
Correct Answer:
200 kg/ha
