Photosynthesis Quiz

Which of the following formulas represents photosynthesis?

• 6 H₂O + 6 O₂ = C₆H₁₂O₆ + 6 CO₂

• C₆H₁₂O₆ + 6 O₂ = 6 H₂O + 6 CO₂

• C₆H₁₂O₆ + 6 CO₂ = 6 H₂O + 6 O₂

• 6 H₂O + 6 CO₂ = C₆H₁₂O₆ + 6 O₂

Which organelle performs photosynthesis?

• Mitochondria

• Nucleus

• Chloroplast

• Ribosome

The main source of energy for all life comes from

• The food we eat.

• The sun in the sky.

• The glucose made by plants.

• Chemical energy in molecules.

Where do the light reactions happen in photosynthesis?

• the mitochondrial membrane

• the stroma.

• the central vacuole.

• the thylakoid membrane.

What is the main purpose of the light reactions in photosynthesis?

• to make the glucose needed in the next step.

• to reflect the green light for the next step.

• to capture energy and make the glucose for the next step.

• to provide energy and electrons for the next step.

Where does the light independent reaction take place?

• the matrix

• the stroma

• the thylakoid membrane

• the cytoplasm

What is one function of the other pigments  besides chlorophyll, in the chloroplast?

• to block damaging wavelengths of light
• to absorb different wavelengths than the chloroplasts
• to provide different colors to the leaves
• to transfer energy to a separate photosystem beside the one using chlorophyll a and b.
