Introduction

Environmental Issues and Solutions

Identifying and Determining Essential Mineral Elements

• The element should be crucial for a plant's growth. In its absence, the plant cannot grow and perform vital functions, leading the plant not to complete its life cycle.
• The element is required specifically by the plant, and its need cannot be replaced by some other element, meaning that any other mineral providence cannot compensate for the deficiency caused by a specific mineral.
• The element directly influences the metabolic activities of the plant.

Types of Essential Mineral Elements

• Essential elements as a part of biomolecules.
• Essential elements as a part of energy-linked chemical compounds.
• Essential elements involved in activating and inhibiting enzyme-linked reactions.
• Essential elements involved in altering the osmotic cell potentials.

Absorption and Functions of Essential Mineral Elements

Absorption of essential mineral elements is through two different processes:

Types of Endocrine Glands

The functions of essential mineral elements are

• They help form the plant body , and some essential elements help make up the structure of the plant, like N and S. Other elements, like Fe, are present in cytochromes.
• The osmotic potential of a plant cell sap is determined with the help of essential elements by regulating the cell’s fluid content.
• The presence of mineral elements also affects cell membrane permeability as they have cations and anions
• Various elements, like copper, iron, and zinc, also speed up the metabolic reactions enhancing the catalytic activities .
• Regulation of toxic minerals by balancing their effect is another function of minerals elements.
• Mineral elements influence the buffer system of plants as upon absorption from the soil, they affect the ion concentration of cells and also regulate the pH of the cell sap.
• The transportation of substances across the phloem to different parts of the plant is regulated by mineral elements like boron and potassium.

• Necrosis occurs when Ca, Mg, K, and Cu deficiency leads to tissue death, mainly affecting the leaf tissues.
• N, K, S, and Mo deficiency has shown that it drastically inhibits cell division.
• When the plant is deficient in N, S, and Mo, it generally shows a delay in flowering.
