Question

Micronutrients are present in plant tissues in concentrations less than ________ of dry matter

• A. 1 mmole Kg${}^{–}1$
• B. 10 mmole Kg${}^{–1}$
• C. 0.1 mmole Kg${}^{–1}$
• D. 2 mmole Kg${}^{–1}$

Answer 1

The correct option is B 10 mmole Kg${}^{–1}$

Plants require nutrients for attaining growth and development. These nutrients when required in large amounts are known as macronutrients and when required in less amounts are known as micronutrients.
Micronutrients include Fe, Mo, Mn, Zn, Cu, etc. These are required less than 10 mmole kg${}^{–1}$.
