C1.3 Photosynthesis Quiz

What does photosynthesis supply to ecosystems?

• Oxygen

• Chemical energy

• Water

• Soil nutrients

What is the main purpose of photolysis in photosynthesis?

• To absorb carbon dioxide

• To split water into hydrogen ions and oxygen gas

• To produce chlorophyll

• To convert glucose into energy

Which gas is released as a waste product during photosynthesis?

• Nitrogen

• Hydrogen

• Oxygen

• Carbon dioxide

What is the chemical formula for glucose produced in photosynthesis?

• C6H12O6

• C5H10O5

• C6H10O5

• C6H12O7

What are the reactants in the photosynthesis equation?

• Glucose and oxygen

• Carbon dioxide and water

• Hydrogen and oxygen

• Nitrogen and water

Which types of chromatography can be used for separating photosynthetic pigments?

• Gas chromatography

• Thin-layer chromatography or paper chromatography

• Ion-exchange chromatography

• Affinity chromatography

What is the role of photosynthetic pigments in the absorption of light?

• Reflect all wavelengths of light

• Absorb all wavelengths of light

• Absorb specific wavelengths of light

• Emit light energy

Why are only some wavelengths of light absorbed by pigments?

• All wavelengths are absorbed equally

• Only wavelengths that match the energy levels of electrons are absorbed

• Wavelengths are absorbed randomly

• Pigments reflect all wavelengths

Why do leaves appear green?

• Because they absorb green light.

• Because they reflect green light.

• Because they do not absorb any light.

• Because they are made of green cells.

What should students be able to determine from data regarding photosynthesis?

• Rates of photosynthesis for oxygen production and carbon dioxide consumption

• The color of leaves

• The temperature of the environment

• The amount of sunlight received
