Explanation: 

Detailed explanation-1: -Nutrient deficiency symptoms occur as yellowing of leaves, interveinal yellowing of leaves, shortened internodes, or abnormal coloration such as red, purple, or bronze leaves. These symptoms appear on different plant parts as a result of nutrient mobility in the plant.

Detailed explanation-2: -An essential nutrient required by the plant in large amounts is called a macronutrient, while one required in very small amounts is termed a micronutrient. Missing or inadequate supplies of nutrients adversely affect plant growth, leading to stunted growth, slow growth, chlorosis, or cell death.

Detailed explanation-3: -Nutrient toxicity occurs when an element is in excess of plant needs and decreases plant growth or qual-ity. Nutrient deficiency or toxicity symptoms often differ among species and varieties of plants.

Detailed explanation-4: -Symptoms caused by nutrient deficiencies are generally grouped into five categories: 1) stunted growth; 2) chlorosis; 3) interveinal chlorosis; 4) purplish-red coloring; and 5) necrosis. Stunting is a common symptom for many deficient nutrients due to their varied roles in the plant.
