Important Topics for NCERT Solutions for Chapter 12 – Mineral Nutrition

The NCERT Class 11 Biology Chapter 12 Mineral Nutrition consists of an extensive number of topics and sub-topics related to mineral nutrition. Make sure that you are well-versed with your concepts. Here is an overview of some of the important concepts of the chapter:

Methods to Study Mineral Requirement in Plants

There are basically two methods to study the mineral requirement in plants, namely, hydroponics and aeroponics. In hydroponics, plants are grown with the help of nutrient solutions. Nutrients are prayed in the air with the help of aeroponics.

Criteria of Essentiality

Some of the criteria of essentiality include that nutrients should be directly involved in the metabolism of a plant, the role of the nutrients should not be replaced by any other nutrients, elements necessary for reproduction and growth, etc.

Macronutrients and Micronutrients

The nutrients that are needed by plants in large quantities are called macronutrients. Micronutrients are nutrients that are needed by the plants in small quantities. Macronutrients include oxygen, phosphorus, sulphur, hydrogen, etc. Micronutrients include iron, zinc, copper, nickel, etc.

Deficiency Symptoms of Essential Elements

The deficiency of certain nutrients hinders the functioning of plants in various ways. The deficiency of potassium causes interveinal chlorosis and wilting of old leaves. Deficiency in phosphorus leads to yellowing and burning of the tips of leaves. Copper deficiency causes dieback of stems and weakening of cell walls. Zinc deficiency causes stunted growth, yellowing between the veins and rosette formation.

Soil as a Reservoir of Essential Elements

Soil provides all the essential nutrients that are detrimental to the growth and the development of plants through the roots. Soil also provides nitrogen-fixing bacteria and microbes that supply air to the roots and holds water in the plant.

Metabolism of Nitrogen

Nitrogen fixation refers to the conversion of nitrogen into ammonia. Two types of nitrogen fixation include physical and biological nitrogen fixation. Physical nitrogen fixation refers to nitrogen fixation under the influence of lightning and thunder. Biological nitrogen fixation relates to the conversion of nitrogen into nitrogenous compounds through the agency of living organisms.
