Photosynthesis Quiz

Where does the light independent reaction (part 1 of photosynthesis) take place?

• phloem

• Stroma
• Thylakoid membrane
• Cytoplasm

Which of the following equations represents the overall chemical reaction for photosynthesis?

• 6O₂+ 6H₂O → C₆H₁₂O₆+ 6O₂

• C₆H₁₂O₆ + 6H₂O→ 6O₂+ 6O₂

• 6CO₂+ 6H₂O→ C₆H₁₂O₆+ 6O₂

• 6O₂ + 6H₂O→ C₆H₁₂O₆ + 6CO₂

Which abiotic factor can increase the rate of photosynthesis?

• Temperature

• Carbon dioxide levels

• Light intensity

• Oxygen concentration

Which organelle is responsible making food (Glucose) using sunlight?

• cytoplasm

• Nucleus

• Chloroplast

• Mitochondria

What structure allows carbon dioxide to enter a plant and oxygen to leave during photosynthesis?

• Roots

• stem

• Stomata

• xylem

How does most of the water needed by the plant get into its leaves?

• The roots absorb it and then it travels up the phloem

• It enters through the stomata

• The roots absorb it and then it travels up the xylem

• The flowers capture water and deliver it to the leaves

Why are plants usually green?

• Because the chlorophyll reflects green light

• Because the chlorophyll absorbs green light

• Because the accessory pigments combine to make green

• Because the accessory pigments only absorb green light

Which of the following light color is absorbed by plants?

• Red

• Green

• yellow

What is photosynthesis?

• The process plants use to turn carbon dioxide and water more carbon dioxide

• The process plants use to chlorophyll and sunlight into air. 
• The process plants use to turn sunlight energy into chemical energy

• The process plants use to turn chemical energy into light energy

Where do the dark reactions (part 2 of photosynthesis) take place? 

• thylakoid membrane
• phloem

• stroma
• granum
