Reason (R): In higher plants, the nitrogenase enzyme is absent.
Both A & R are true and R explains A
Both A & R are true and R does not explain A
A is true and R is False
Both A & R false
Nitrogenase can only break N ≅ N bond and it is absent in higher plants, hence they cannot utilize N2 present in the air.
Assertion (A): Sugars are synthesized in the bundle sheath cells of maize plants.
Reason (R): Calvin cycle occurs in the bundle sheath cells of C4 plants.
Assertion (A): Macronutrients are generally present in plant tissues in large amounts, in excess of 10 m mole kg−1 of dry matter.
Reason (R): Micronutrients are needed in very small amounts, less than 10 m mole kg−1 of dry matter.
