A scientist is studying the role of micronutrients in plant growth. They observe that a particular plant species exhibits stunted growth and interveinal chlorosis in young leaves. Which micronutrient deficiency is MOST likely responsible for these symptoms?
Manganese
Zinc
Copper
Iron
A plant experiencing calcium deficiency shows necrotic spots on its leaves and stunted root growth. This is primarily because calcium:
Is a mobile element easily transported within the plant.
Acts as an enzyme activator in various metabolic pathways.
Is a component of chlorophyll and other photosynthetic pigments.
Is crucial for cell wall integrity and membrane permeability.
Which pair of elements are predominantly found in older leaves due to their immobility within the plant?
Nitrogen and Potassium
Magnesium and Phosphorus
Calcium and Boron
Iron and Manganese
Which micronutrient is essential for the synthesis of auxin, a plant hormone crucial for growth and development?
Copper
Molybdenum
Zinc
Boron
A researcher observes that a plant exhibits stunted growth, delayed flowering, and reduced pollen viability. Further analysis reveals a deficiency in a specific micronutrient that plays a role in pollen germination and cell division. Which micronutrient is MOST likely deficient?
Iron
Manganese
Copper
Boron
A patient presents with severe muscle weakness, difficulty walking, and loss of tendon reflexes. Further investigation reveals impaired glucose metabolism and cardiac abnormalities. These symptoms are MOST likely associated with a deficiency of:
Vitamin D
Vitamin B12
Thiamine (Vitamin B1)
Niacin
A child displays stunted growth, impaired wound healing, and skin lesions. Biochemical analysis reveals decreased collagen synthesis. Which pair of nutrient deficiencies is MOST likely responsible for these symptoms?
Iron and Vitamin A
Zinc and Vitamin C
Copper and Vitamin D
Magnesium and Vitamin K
A plant exhibits interveinal chlorosis in its young leaves, while older leaves remain relatively unaffected. This symptom is indicative of a deficiency in which micronutrient that is relatively immobile within the plant?
Magnesium
Iron
Potassium
Nitrogen
Which of the following deficiency symptoms is NOT correctly paired with the deficient nutrient?
(a) Necrosis of leaf tips - Calcium
(b) Heart rot in sugar beet - Boron
(c) Whiptail in cauliflower - Molybdenum
(d) Dieback of shoots - Copper

A patient experiences impaired dark adaptation, frequent infections, and dry skin. Which fat-soluble vitamin deficiency is MOST likely responsible?
Vitamin D
Vitamin E
Vitamin K
Vitamin A
