Photosynthesis Quiz

What is photosynthesis?

• The process by which animals convert glucose into energy

• The process by which plants, some bacteria, and some protists use sunlight to produce glucose from carbon dioxide and water

• The process by which plants absorb carbon dioxide and release oxygen without sunlight

• The process by which plants convert oxygen into carbon dioxide

Which pigment is primarily responsible for the conversion of sunlight energy into chemical energy during photosynthesis?

• Xanthophyll

• Carotenoid

What are the common features of all chlorophylls?
