Plant Mineral Nutrition Quiz

What are the two main categories of nutrients required by plants?

• Organic and inorganic

• Macronutrients and micronutrients

• Primary and secondary

• Essential and non-essential

Which macronutrient is essential for the synthesis of nucleic acids and proteins?

• Phosphorus

• Nitrogen

• Calcium

• Magnesium

Which micronutrient is crucial for chlorophyll synthesis?

• Zinc

• Copper

• Manganese

• Iron

What does Cation Exchange Capacity (CEC) measure?

• Soil's ability to hold and exchange cations

• Soil's pH level

• Soil's moisture content

• Soil's ability to hold and exchange anions

Which type of soil typically has a higher CEC?

• Saline soils

• Sandy soils

• Clay soils

• Loamy soils

What effect does soil pH have on nutrient availability?

• Lower pH increases cation exchange capacity

• Higher pH increases nutrient leaching

• Higher pH increases negative charges on soil particles

• Lower pH increases nutrient retention

Which process requires ATP for nutrient uptake?

• Active transport

• Facilitated diffusion

• Mass flow

• Diffusion

What is the role of auxins in plants?

• Stimulate photosynthesis

• Enhance chlorophyll production

• Regulate root growth

• Promote flowering

What is a common symptom of mineral deficiency in plants?

• Increased fruit production

• Enhanced root development

• Excessive growth

• Leaf discoloration

What are hyperaccumulators?

• Plants that have low nutrient uptake

• Plants that accumulate heavy metals

• Plants that require high moisture

• Plants that grow in acidic soils
