Mineral Nutrition NEET Questions with Answers
Mineral Nutrition in Plants: Mineral nutrition is important for the growth and development of plants, as it involves the absorption and utilization of minerals from the soil. These minerals, categorized into macronutrients (e.g., nitrogen, phosphorus, potassium) and micronutrients (e.g., iron, manganese, zinc), are vital for various physiological processes. Macronutrients are required in larger quantities and play key roles in processes like photosynthesis, protein synthesis, and cell division, while micronutrients, needed in smaller amounts, are essential for enzyme function and other metabolic activities.
Importance in Human Nutrition: For NEET aspirants, understanding mineral nutrition is equally important for human physiology. Essential minerals like calcium, potassium and iron contribute to bone health, nerve function and oxygen transport, respectively. Deficiencies or imbalances in mineral intake can lead to various health issues, such as anemia (iron deficiency), osteoporosis (calcium deficiency), or muscle cramps (potassium deficiency). Hence, a balanced diet rich in both macro and micronutrients is essential for maintaining overall health and preventing diseases.

FAQs
- What is mineral nutrition in plants?
Answer. Mineral nutrition refers to the absorption, distribution and utilization of inorganic substances or minerals by plants. These minerals are essential for various physiological and biochemical processes.
- Why are minerals essential for plants?
Answer. Minerals are crucial for plants because they play vital roles in several physiological processes such as photosynthesis, respiration and enzyme activation. They also contribute to the structural components of cells.
- What are macronutrients and micronutrients?
- Macronutrients are minerals required by plants in larger quantities. Examples include nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S).
- Micronutrients are required in smaller amounts. Examples include iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), molybdenum (Mo), boron (B) and chlorine (Cl).
- What is the difference between mobile and immobile nutrients?
- Mobile nutrients can move from older tissues to newer ones when there is a deficiency. Examples include nitrogen, phosphorus and potassium.
- Immobile nutrients remain in the older tissues, leading to deficiency symptoms in newer tissues. Examples include calcium, sulfur and iron.
- What are the symptoms of mineral deficiency in plants?
- Nitrogen Deficiency: Yellowing of older leaves (chlorosis), stunted growth.
- Phosphorus Deficiency: Dark green or purplish discoloration of leaves, delayed flowering.
- Potassium Deficiency: Browning of leaf edges (marginal necrosis), weak stems.
- Calcium Deficiency: Deformed leaves, blossom-end rot in fruits.
- Iron Deficiency: Interveinal chlorosis (yellowing between leaf veins) in young leaves.
- How do plants absorb minerals from the soil?
Answer. Plants absorb minerals from the soil through their root hairs. The minerals are taken up in ionic forms, such as nitrate (NO₃⁻), ammonium (NH₄⁺), phosphate (H₂PO₄⁻) and potassium (K⁺). The absorption process involves both passive and active transport mechanisms.
