Plant Nutrition and Photosynthesis Quiz

What is the primary function of chlorophyll in photosynthesis?

• To absorb water
• To capture light energy
• To release oxygen
• To transport nutrients

Which of the following is NOT a raw material required for photosynthesis?

• Carbon dioxide
• Glucose
• Water
• Light energy

What is the main product of photosynthesis?

• Oxygen
• Carbon dioxide
• Glucose
• Starch

How do plants primarily absorb carbon dioxide?

• Through roots
• Through stomata
• Through chlorophyll
• Through flowers

What happens to the rate of photosynthesis when light intensity increases?

• It decreases
• It remains the same
• It increases until a saturation point
• It stops completely

Which mineral is essential for the synthesis of chlorophyll?

• Nitrate
• Magnesium
• Calcium
• Iron

What is the balanced chemical equation for photosynthesis?

• 6 CO2 + 6 H2O → C6H12O6 + 6 O2
• C6H12O6 + 6 O2 → 6 CO2 + 6 H2O
• 6 O2 + 6 H2O → 6 CO2 + C6H12O6
• 6 CO2 + C6H12O6 → 6 O2 + 6 H2O

What role does glucose play in plants?

• It is a waste product
• It is used for energy and growth
• It is only stored
• It is converted to oxygen

Which factor does NOT affect the rate of photosynthesis?

• Light intensity
