CSHS PreAP Biology Unit 5 - Photosynthesis

What wavelengths of light are ABSORBED most by chlorophyll?

• purple and green

• red and blue

• black and orange

• yellow and green

Most plants appear green because chlorophyll

• absorbs green light.
• absorbs violet light.
• reflects green light.
• does not absorb violet light.

Which of the following is the correct equation for PHOTOSYNTHESIS?

• 6CO₂ + 6H₂O --> 6O₂ + C₆H₁₂O₆

• 6CO₂ + C₆H₁₂O₆ + 6H₂O --> O₂

• 6O₂ + 6H₂O --> 6CO₂ + C₆H₁₂O₆

• C₆H₁₂O₆+ 6O₂ ---> 6H₂O + 6CO₂
