Chapter 12 – Mineral Nutrition
Mineral Nutrition is an important chapter in Class 11 Biology that explains how plants obtain and utilize essential mineral elements from the soil. Plants require various macronutrients such as nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, and micronutrients like iron, manganese, zinc, copper, boron, molybdenum, chlorine, and nickel for proper growth and development.
This chapter discusses the criteria for essentiality of elements, the role of each nutrient, and the deficiency symptoms caused by their absence. It also covers important concepts such as hydroponics, nitrogen cycle, biological nitrogen fixation, and the role of Rhizobium in leguminous plants. Understanding mineral nutrition helps students grasp plant metabolism and productivity, which is crucial for exams like CBSE and NEET.
