Photosynthesis Quiz

What pigment is responsible for capturing light energy during photosynthesis?

• Hemoglobin

• Chlorophyll

• Xanthophyll

• Carotene

Write down the chemical equation for photosynthesis.

• 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2

• 6CO2 + 6H2O -> C6H12O6 + 6O2

• 6CO2 + 6H2O + ATP -> C6H12O6 + 6O2

• CO2 + H2O + light energy -> CH2O + O2

In which part of the plant does photosynthesis primarily occur?

• Leaves

• Roots

• Stems

• Flowers

Name the two reactants required for photosynthesis to take place.

• Sunlight and soil

• Oxygen and nitrogen

• Carbon dioxide and water

• Glucose and starch

What are the two main products of photosynthesis?

• Starch and nitrogen

• Fructose and carbon dioxide

• Water and sunlight

• Glucose and oxygen

Define photosynthesis in one sentence.

• Photosynthesis is the process of converting water into oxygen.

• Photosynthesis is the process of converting sunlight into energy.

• Photosynthesis is the process of converting carbon dioxide into water.

• Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, carbon dioxide, and water.

Which organelle in plant cells is responsible for photosynthesis?

• Mitochondria

• Endoplasmic reticulum

• Nucleus

• Chloroplasts

What environmental condition is essential for photosynthesis to happen?

• Light

• Temperature

• Sound

• Water

How does chlorophyll contribute to the process of photosynthesis?

• Chlorophyll regulates the temperature for photosynthesis

• Chlorophyll converts carbon dioxide into glucose

• Chlorophyll releases oxygen during photosynthesis

• Chlorophyll absorbs light energy

What is the role of leaves in the process of photosynthesis?

• Leaves absorb water and release oxygen during photosynthesis.

• Leaves store excess energy from photosynthesis in the form of glucose.

• Leaves regulate the temperature of the plant during photosynthesis.

• Leaves contain chlorophyll that captures sunlight and converts it into energy for photosynthesis.
