Class 11 Biology Chapter 12 Mineral Nutrition: Important Topics

Mineral nutrition refers to inorganic nutrients found naturally in the soil and deep underground, as well as food required for the normal functioning of animal and plant bodies. Nutrients serve a variety of purposes in plant cells and participate in a variety of metabolic processes. Minerals are stored in the soil. Soil, in addition to minerals, contains water and air, as well as useful microbes such as nitrogen-fixing bacteria.

Essential Mineral Elements

Minerals can be further divided into two broad categories based on their quantitative requirements:

Macrominerals: Phosphorous, carbon, sodium, nitrogen, potassium, silicon, magnesium, hydrogen, calcium, oxygen, selenium, and sulfur are considered to be macrominerals and are generally found in large amounts in plant tissues.
Microminerals: Iron, boron, nickel, manganese, copper, zinc, cobalt, chlorine, and molybdenum are called microminerals or trace elements and are required by plants in small amounts.
