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. 

Since mineral nutrition NEET is an important part of NEET syllabus, students appearing for the same can also go through these questions for a quick revision. Therefore, keeping the requirements of students in mind the questions given below cover all the essential topics within the chapter.

FAQ (Frequently Asked Questions)

1. What is the definition of macronutrients and micronutrients?

Elements consumed by plants in large quantities are known as macronutrients. Examples include calcium, oxygen, nitrogen, hydrogen, magnesium etc. On the other hand, micronutrients, also called trace elements, are those components which are needed by plants in small quantities. Examples are iron, zinc, copper, manganese etc.

2. What is hydroponics?

The method of growing plants in a mineral nutrient solution in water without the presence of soil is called hydroponics. This method is crucial to identify essential elements and deficiency syndromes.

3. What is the primary criterion based on which an element is considered essential for plants?

To be considered essential, an element must be crucial for a plant’s life processes and without the absence of which it will show deficiency syndrome.
