Micronutrients are present in plant tissues in concentrations less than ____of dry matter.

Options

A. 1 m mole `Kg^(-1)`
B. 10 m mole `Kg^(-1)`
C. 0.1 m mole `Kg^(-1)`
D. 2 m mole `Kg^(-1)`

Answer

B

Explanation

Microelements (micronutrients) are those essential elements which are required by plants in small amounts, equal of less than 10 mmole `Kg^(-1)` of dro matter. Microelements are mostly involved in the functioning of enzymes, as cofactors or metal activators. They are eight in number- Fe, Zn, Mn, B, Cu Mo, Cl and Ni.
