Question

Plants usually require micronutrients in very low concentrations. However, if the concentration of micronutrients increases, it leads to ________.

• A. Toxicity
• B. Cell differentiation
• C. Cell elongation
• D. Deficiency symptoms

Answer 1

The correct option is A

Toxicity

There are specific concentrations, below which the micronutrients are useful to the plants. However, beyond these critical concentrations, the micronutrients turn toxic to the plants and may cause a variety of symptoms. This is called as toxicity. The critical concentrations of each micronutrient is different for different elements.
