Mineral Nutrition MCQs

Under the topic mineral nutrition, you will learn in detail about essential mineral elements that plants require for growth and development. In addition to that, you will also learn how plants absorb these essential nutrients, deficiency symptoms and significance of nitrogen as a micronutrient and biological nitrogen fixation.

Before moving on to the MCQ on nutrition, let us go through some important concepts from this chapter. Notably, plants being autotrophs, they derive all these essential elements from the soil.

An essential element can be defined as a component that is crucial for the growth of a plant and the deficiency of which causes disease and hampers its life cycle. Essential elements can be classified into two types based on the amount required by a plant. These are macronutrients and micronutrients.

The following MCQ on minerals and trace elements will enable you to gain more clarity of the concepts discussed within this chapter. Aside from that, practising these questions will also help you to revise this section thoroughly before examinations.
