What are the two categories of essential mineral elements in plants?
Macronutrients and Micronutrients.
Name three macronutrients required by plants.
Nitrogen, phosphorus, and potassium.
What is the function of nitrogen in plants?
It is a key component of enzymes, protoplasm, nucleic acids, and chlorophyll.
What is a deficiency symptom of nitrogen in plants?
Stunted growth and yellowing of leaves (chlorosis).
How does phosphorus benefit plants?
Promotes strong root development, supports fruit formation, and is essential for coenzymes.
What is a sign of phosphorus deficiency in plants?
Poor root development and stunted growth.
What role does sulfur play in plants?
Important for forming certain proteins in the protoplasm.
What happens to plants with a sulfur deficiency?
Yellowing of leaves and stunted growth.
What is the function of potassium in plants?
Helps form amino acids, activates photosynthesis, and promotes crop maturation.
What is a potassium deficiency symptom?
Yellowing and browning at leaf margins and premature plant death.
Why is magnesium essential for plants?
It is crucial for chlorophyll formation and activates many coenzymes.
What does a magnesium deficiency cause?
Chlorosis (yellowing of leaves) and poor growth.
How does calcium help plants?
It aids in storing proteins and carbohydrates and provides structural support through cell wall formation.
What are symptoms of calcium deficiency?
Poor root development, death of terminal buds, and stunted growth.
What is the role of iron in plant growth?
It is essential for protein formation and chlorophyll synthesis.
What deficiency symptoms are associated with iron?
Yellowing of leaves and stunted growth.
Name three micronutrients required by plants.
Copper, zinc, and boron.
What is the function of copper in plants?
It is a component of respiratory enzymes.
What is the deficiency symptom of copper?
Poor growth.
Why is manganese important for plants?
It activates certain enzymes.
What happens with manganese deficiency in plants?
Death of shoots.
What is the function of chlorine in plants?
It is essential for oxygen release during photosynthesis.
What are symptoms of chlorine deficiency?
Wilting of leaves, necrosis, and reduced growth.
What role does molybdenum play in plants?
It activates enzymes for nitrate reduction and nitrogen fixation.
What happens when plants lack molybdenum?
Poor growth.
How does boron benefit plants?
It is involved in the movement of sugars and calcium within the plant.
What are symptoms of boron deficiency?
Brown shoots and poor pollen tube growth.
What is the role of zinc in plants?
Activates enzymes, supports auxin production, and aids protein synthesis.
What is the deficiency symptom of zinc?
Poor growth.
How does silicon help plants?
It contributes to cell wall formation.
