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
Which element is NOT essential for the synthesis of chlorophyll?
Magnesium
Nitrogen
Iron
Sodium
Molybdenum deficiency primarily affects which metabolic process in plants?
Photosynthesis
Respiration
Nitrogen fixation
Transpiration
Which element is a constituent of the middle lamella in plant cells?
Potassium
Magnesium
Calcium
Iron
Which group of elements are predominantly involved in maintaining osmotic potential in plants?
Calcium, Magnesium, Sulfur
Iron, Manganese, Zinc
Potassium, Chloride, Sodium
Nitrogen, Phosphorus, Potassium
Zinc is essential for the activity of which plant hormone?
Gibberellin
Cytokinin
Auxin
Ethylene
