Task: Class Definition Understanding (ontology: Food_Agriculture/Crop_Ontology)

Which of the following definitions best describes 'Stomatal conductance-leaf porometer method'?

A. Measure the fresh weight of vines sample and record it
B. A leaf porometer is used to estimate stomatal conductance by simply clipping the sensor head onto a leaf and record stomatal conductance within 30 seconds
C. Measure the total monomeric anthocyanin content of the storage root and record it
D. Measure the beta-carotene concentration of the boiled storage root in fresh weight basis and record it

Answer: A leaf porometer is used to estimate stomatal conductance by simply clipping the sensor head onto a leaf and record stomatal conductance within 30 seconds
