Answer

Mineral nutrition refers to the process by which plants absorb inorganic ions from the soil, use them for growth, development, and reproduction. These minerals are essential for building plant structu…

Answer

Essential elements are those inorganic elements that are absolutely necessary for normal growth and reproduction of plants. They cannot be replaced by any other element and are directly involved in pl…

Answer

1. The element must be absolutely necessary for normal growth and reproduction. 2. The requirement must be specific and irreplaceable. 3. The element must be directly involved in plant nutrition or me…

Answer

Plants require 17 essential elements. These include carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, molybdenum, chlorine, a…

Answer

Macronutrients are required in large amounts (e.g., N, P, K, Ca, Mg, S), while micronutrients (or trace elements) are needed in very small quantities (e.g., Fe, Zn, Cu, B, Mn, Mo, Cl). Deficiency of e…

Answer

The macronutrients are: Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg), and Sulfur (S).

Answer

Carbon, hydrogen, and oxygen form the basic structural components of carbohydrates, proteins, fats, and nucleic acids. They make up the backbone of organic molecules in plants and are obtained from CO…

Answer

Critical elements are those that play a vital role in the life cycle of plants. Nitrogen (N), Phosphorus (P), and Potassium (K) are called critical elements because they are involved in key processes …
