Chapter Overview
This chapter focuses on the role of minerals in the life of a plant. It covers the essential nutrients, their types, methods of absorption, deficiency symptoms, and mechanisms like nitrogen fixation. The chapter also discusses the criteria for essentiality and the biological importance of key nutrients.
Important Keywords
- Essential Elements: Elements required for normal growth and reproduction of plants.
- Macronutrients: Nutrients required in large amounts (e.g., Nitrogen, Potassium).
- Micronutrients: Nutrients needed in trace amounts (e.g., Iron, Zinc).
- Deficiency Symptoms: Visible effects due to lack of essential nutrients.
- Hydroponics: Method of growing plants in a nutrient solution without soil.
- Symbiotic Nitrogen Fixation: Mutual relationship between plants and microbes (e.g., Rhizobium in legumes).
- Ammonification: Conversion of organic nitrogen into ammonia.
- Nitrification: Conversion of ammonia into nitrites and nitrates.
- Assimilation: Uptake of nitrates by plants and incorporation into proteins.
