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

Most of the oxygen in the Earth’s atmosphere was produced by —

• a big explosion

• photosynthesis

• digestion

• metabolism

If we enclosed a plant in an air-proof bottle, what would happen to the rate of photosynthesis 

• Gradually slow down to zero because CO₂ is used up
• Shows a constant rate as long as the light remains on
• Gradually speeds up because O₂ builds up
• Gradually slows down because glucose builds up
